今天的阅读小分队我们来了解一下在国外备受年轻人欢 “Pinterest”（拼趣），它主要是基于API建立起来的一个图片社交网站。不过，当我们的眼球被上面各种眼花缭乱的图片吸引过去，Pin上自己喜欢的图片的时候，其实商家这个时候就开始盯上你了，通过揭取你的偏好从而向你营销。尽管Pinterest在用户隐私保护方面做出了努力，但是在大数据时代，对于商家，其实你早已经“一丝不挂”了。

此次是楼主第一次在阅读小分队作为编辑发帖，而在此之前则一直是小分队的忠实读者，这种角色的转换感觉很棒！文章都不是很难，希望大家在紧张的周一结束的时候放松一下！enjoy！

Part I: Speaker

We're All Hawking Products Now

You post photos on social media sites for the enjoyment of your family and friends. But your snapshots are also a potential gold mine of information about what you spend money on for those sites and the companies that advertise on them.

Artificial intelligence software is on the horizon that can spot brands like Nike or Coke even in images without text or tags. Google, Facebook and other deep-pocketed investors are accelerating this software’s development. Even startup photo-sharing service Pinterest got in on the action earlier this year by buying the even more “start-uppy” VisualGraph, whose software could be used to find and link photos with similar content.

In general the software winning these investments uses machine vision, image recognition and/or visual search algorithms to identify objects and shapes as well as textures. One startup called Ditto Labs makes a search engine that specifically examines digital images for logos and brands.

So next time you’re chowing down in McDonald’s, smile for that selfie. You’re feeding that company’s bottom line and probably helping a tech startup earn its next million. On second thought, why are YOU smiling?

A Scrapbook on the Web Catches Fire
By DAVID POGUE   |  15 Feb 2012

[Warm up]
“OMG! Did you see Brad Pitt’s post on Digglr last night?”
“No, I was too busy cruising Cr.us.ta.ce.an. What did he say?”
“OMG, it was all over Regurgtatr!”

Have you ever had the sinking feeling that the online world is moving so fast that you’ll never catch up?

Every year, there’s another hot new online service, another drain into which to pour your time. Question: Once you’re on Facebook and Twitter and Foursquare and Google Plus and Tumblr and LinkedIn and Instagram and Reddit and Path — when, exactly, do you have time left over for a life?

Well, never mind. Incredibly, yet another free site has become white-hot popular, because it’s found yet another purpose not quite served by anyone else. It’s Pinterest.com, which recently laid claim to being the fastest Web site in history to break the 10-million-visitors-a-month threshold. It’s suddenly cropping up in conversation, online and off, with surprising frequency.
[152 words]

[Time2]
Pinterest is a pinboard for online photos. Multiple pinboards, actually, each an individual page in your Pinterest account. You can make one for Cool Craft Ideas, another for Kitchen Redo Concepts, a third for Places to See Before I Die. Or maybe Books I’ve Read, Ideas for the Wedding, Best Web Comics. The sky’s the limit.

(Unlike most start-up Web site names, “Pinterest” actually makes sense. You pin things based on your interests.)

There are several keys to Pinterest’s success, but one of them is the simplicity and pleasure of adding a photo to one of your boards. As you surf the Web each day, whenever you see something that looks interesting or inspiring or funny, you click the Pin It button on your bookmarks bar.

Installing that button there is the only even remotely technical part of using Pinterest. Then again, if you don’t know how to add a bookmark to your Web browser, you have more pressing challenges than mastering the latest social networking sites.

Once you click Pin It, you’re shown a tidy array of all the images that appear on the current Web page. Click the one you want, choose which of your boards should collect this image, type a caption, and click Pin It. (Tip: If you highlight some text on a Web page before clicking Pin It, the selected text becomes the caption for your pinboard item.)

When you revisit your Pinterest pages, you’ll see that your newly found image has joined the others on the specified pinboard.

The ability to round things up into tidy collections is powerful and visual. It’s like virtual scrapbooking, or maybe like tearing interesting articles out of the paper.
[281 words]

[Time 3]
Often, the pinboards people create are inspirational: Awesome Vacation Spots, Cool Hairstyles, Yummy-Looking Recipes. Others are funny — they represent items you’ve come across on the funny-and-weird-items sites like StumbleUpon and IWasteSoMuchTime.com. And since this is such a visual site, there’s a lot of beauty: Beautiful People, Beautiful Things, Beautiful Clothes.

If all this talk of kitchens, recipes, crafts and beauty makes you think that Pinterest seems to be female-oriented, you’re right. The company says that women make up more than 80 percent of its members.

The social aspects of Pinterest are surely another reason for that statistic. Whenever you see a juicy item that somebody else has pinned, you can repin it, with a single click, to one of your own boards. In this way, great ideas and photos propagate quickly. You can also “like” an item or comment on it.

Furthermore, if you find somebody whose tastes you like, you can “follow” her (either one board or all of her boards). Her stuff shows up on your Pinterest home page in real time, as she pins stuff.

You can also set up collaborative pinboards, where people you approve can contribute to one of your boards. That’s a sensational feature when your friends or your family members are trying to brainstorm ideas for a wedding, vacation, baby shower or renovation. Everybody chimes in with ideas, comments and votes on the submissions so far. You’re spared an awful lot of “What do you guys think of this?” e-mails.
[247 words]

[Time 4]
In the end, three things make Pinterest so refreshing.

First, it’s pure, uncluttered and non-blinky. There are no ads, scrolling columns or pop-up anything.(The company doesn’t say it’s still figuring out ways to make money from this thing, but clever bloggers have already discovered one way. You know how Amazon.com offers an “affiliate program?” That’s where you get a referral fee, a small percentage of any purchase, whenever somebody follows a link from your own Web site to Amazon’s and then buys something. Lots of online stores offer similar programs. Well, when one of your Pinterest photos links to a product for sale online, Pinterest quietly modifies the link to insert its own affiliate code, so that Pinterest gets the referral fee. The revelation did raise some eyebrows, but you can change the link back, if you want.)

Second, Pinterest is unlike Twitter, Facebook and their ilk because you’re not just broadcasting, or even principally broadcasting. You create Pinterest boards for your own use, your own memory-jogging, your own inspiration. If other people find joy or use from what you’ve put together, great — but you can get tremendous mileage from Pinterest even without a following, which you can’t say about other social sites.

Finally, Pinterest gives you a break from the usual goal of social sites: self-absorption, self-documenting and self-promotion. As a Huffington Post post put it recently, Facebook and Twitter posts tend to “come with the silent subtext, ‘Here’s how great I am.’ On Pinterest, the tone seems to be ‘Wouldn’t this be great?’ ”

That’s not to say that there isn’t room for improvement. There doesn’t seem to be any way to keep a pinboard private. For example, every pinboard is available to everyone else on Pinterest. Now and then, you might not want to advertise all of your aspirations. (“Nose Shapes to Consider for My Cosmetic Surgery,” for example.)
[312 words]

[Time 5]
Right now, you need a Facebook or Twitter account to join Pinterest — either that, or an invitation. You can get one from a current member, or request one from Pinterest itself; fortunately, the company liberally grants these requests.

It’s also worth noting that Pinterest has already been invaded by commercial interests. (Sooner or later, that seems to happen to everything online that starts with grass-roots success: Web sites, podcasts, Twitter, Facebook.) Travel companies, housewares companies, jewelry companies and others have Pinterest accounts.

With a couple of clicks, you can add a price banner to the corner of a photo. And since clicking any photo on a Pinterest board takes you to the Web site from which it came, a Pinterest board is a screamingly obvious setup for an online catalog. Click a photo, jump to the page where you can buy it.

So far, the commercial presence is subtle, and of course you don’t have to follow or look at companies’ pages. Then again, some of them actually contribute, quietly and tastefully, to the overall Pinterest feeling. Whole Foods, for example, has attracted more than 19,000 followers for its “Super Hot Kitchens” page.

Pinterest is shrewdly growing just enough tentacles to keep it accessible and visible. There’s a nice Pinterest iPhone app, for example; an excellent Search box for finding stuff across all Pinterest accounts; a “Pin This” button you can add to your own Web site; and an option to have your newly pinned images show up on your Facebook timeline.

It might seem hard to believe, but yes, even in the Facebook-Twitter-Tumblr-LinkedIn era, there’s still room for yet another successful, popular social media site. At least there’s room online. Whether there’s enough room in your busy life is a different question.

Pinterest Allows Users to Opt Out of Being Tracked
By NICK BILTON  |  26 Jul 2013

[Time 6]
In Silicon Valley there are hundreds of companies that track people’s habits with the hopes of offering more intrusive advertising. There are, in comparison, very few Valley start-ups that give people the opportunity to opt out of that tracking.

On Friday, Pinterest, which allows users to share photographs and other media on custom “pinboards,” joined the short list of companies that do give people that option.

Pinterest is doing this by enabling the Do Not Track feature in certain Web browsers that allows people to avoid cookies that collect personal information as well as any third-party cookies, including those used for advertising.

In May 2012 Twitter began offering this feature to people who use the social network. But the Do Not Track functionality will work only if a Web site agrees to acknowledge it.

As for people who do not select the Do Not Track feature, Pinterest will be watching over their shoulders more than it has in the past. As Twitter did in 2012, Pinterest introduced a new feature that it says will help surface better content to users.

At the same time it announced the Do Not Track option, the company added a new “board suggestions” component to its site. It will figure out the right type of recommendations for content by tracking the type of Web sites someone has visited that included a “Pin” button.

For example, if you visit a cooking Web site that displays the Pinterest Pin, and then go to Pinterest’s Web site, you will see recommendations for cooking-related pinboards.

In a blog post on the company’s Web site, Pinterest said: “We’re excited to offer everyone a more personal experience, but we also understand if you’re not interested. We respect Do Not Track as an option for people who want to turn off this collection of browsing activity from other sites.”
[307 words]

[End up]
Privacy groups lauded the company’s decision to allow people to avoid being tracked online.

“It’s good to see some prominent companies come forward and adopt these standards,” said Kurt Opsahl, a senior staff lawyer with the Electronic Frontier Foundation, a nonprofit privacy group, in a phone interview. “By doing so they are saying ‘we’re going to respect people’s privacy preferences.’”

Joseph Lorenzo Hall, a senior staff technologist with the Center for Democracy & Technology, a nonprofit policy group in Washington, said it is important for more companies to follow suit and provide people with the ability to avoid being tracked across the Web.

“Including Twitter, Pinterest is another major first party that has decided to listen to desires of users and offer them this choice,” Mr. Hall said. He noted that the effort behind Do Not Track remains the same: “Provide users simple and usable ways to signal that they don’t want opaque third-parties creating profiles of their online behavior.”

The Do Not Track initiative has recently been embroiled in its own spat of controversy as advertisers feel threatened by the technology. But that hasn’t stopped Pinterest from giving people an option.

“While consensus around the technical specs remains elusive, people are making a choice when they turn on Do Not Track,” said Mike Yang, general counsel of Pinterest, in an e-mail. “We’re going to respect that choice.

Smile! Marketing Firms Are Mining Your Selfies
Photo-Sharing Sites Are Being Scanned to Find Brands, Target Ads
By DOUGLAS MACMILLAN and ELIZABETH DWOSKIN   |   Oct. 9, 2014

[Paraphrase 7]
Most users of popular photo-sharing sites like Instagram, Flickr and Pinterest know that anyone can view their vacation pictures if shared publicly.

But they may be surprised to learn that a new crop of digital marketing companies are searching, scanning, storing and repurposing these images to draw insights for big-brand advertisers.

Some companies, such as Ditto Labs Inc., use software to scan photos—the image of someone holding a Coca-Cola can, for example—to identify logos, whether the person in the image is smiling, and the scene’s context. The data allow marketers to send targeted ads or conduct market research.

Others, such as Piqora Inc., store images for months on their own servers to show marketers what is trending in popularity. Some have run afoul of the loose rules on image-storing that the services have in place.

The startups’ efforts are raising fresh privacy concerns about how photo-sharing sites convey the collection of personal data to users. The trove is startling: Instagram says 20 billion photos have already been shared on its service, and users are adding about 60 million a day.

The digital marketers gain access to photos publicly shared on services like Instagram or Pinterest through software code called an application programming interface, or API. The photo-sharing services, in turn, hope the brands will eventually spend money to advertise on their sites.

Privacy watchdogs contend these sites aren’t clearly communicating to users that their images could be scanned in bulk or downloaded for marketing purposes. Many users may not intend to promote, say, a pair of jeans they are wearing in a photo or a bottle of beer on the table next to them, the privacy experts say.

“This is an area that could be ripe for commercial exploitation and predatory marketing,” said Joni Lupovitz, vice president at children’s privacy advocacy group Common Sense Media. “Just because you happen to be in a certain place or captured an image, you might not understand that could be used to build a profile of you online.”

In recent years, startups have begun mining text in tweets or social-media posts for keywords that indicate trends or sentiment toward brands. The market for image-mining is newer and potentially more invasive because photos inspire more emotions in people and are sometimes open to more interpretation than text.

Instagram, Flickr and Pinterest Inc.—among the largest photo-sharing sites—say they adequately inform users that publicly posted content might be shared with partners and take action when their rules are violated by outside developers. Photos that are marked as private by users or not shared wouldn’t be available to marketers.

There are no laws forbidding publicly available photos from being analyzed in bulk, because the images were posted by the user for anyone to see and download. The U.S. Federal Trade Commission does require that websites be transparent about how they share user data with third parties, but that rule is open to interpretation, particularly as new business models arise. Authorities have charged companies that omit the scope of their data-sharing from privacy policies with misleading consumers.

The FTC declined to comment.

The photo sites’ privacy policies—the legal document enforced by law as promises to consumers—vary in wording but none of them clearly convey how third-party services treat user-posted photos.

For example, the privacy policy of Instagram, which is owned by Facebook Inc., directs its more than 200 million users to a separate document that explains rules for developers. Pinterest and Flickr, owned by Yahoo Inc., have no explicit mention of third-party developers in their privacy policies. Other popular sites for photos, including Twitter Inc. and another Yahoo-owned site, Tumblr, warn users they may share nonprivate content with third parties.

While Facebook is one of the largest photo-sharing sites, the fact that most of its users restrict their photos’ access with privacy controls has deterred outside developers from mining those images. Developers commonly use Facebook’s API to pull in profile photos of its members but not for marketing purposes.

An Instagram spokesman said its partnerships with developers don’t “change anything about who owns photos, or the protections we have in place to keep our community a safe place.” Flickr said it takes steps to prevent outside developers from scanning photos on its site in bulk.

Pinterest said “our API only provides public information to a handful of partners intended to help their clients understand the performance of their content on Pinterest.”

Spokeswomen for Tumblr and Twitter declined to comment.

Jules Polonetsky, the director of Future of Privacy Forum, an advocacy group funded by Facebook and other tech companies, said users should assume that companies are scanning sites for market research if their photos are publicly viewable.

But the boom in image-scanning technologies could lead to a world in which people’s offline behavior, caught in unsuspecting images, increasingly becomes fodder for more personalized forms of marketing, said Peter Eckersley, technology-projects director for the Electronic Frontier Foundation.

Moreover, the use of software to scan faces or objects in photos is so new that most sites don’t mention the technology in their privacy policies.

Advertisers such as Kraft Foods Group Inc. pay Ditto Labs to find their products’ logos in photos on Tumblr and Instagram. The Cambridge, Mass., company’s software can detect patterns in consumer behavior, such as which kinds of beverages people like to drink with macaroni and cheese, and whether or not they are smiling in those images. Ditto Labs places users into categories, such as “sports fans” and “foodies” based on the context of their images.

Kraft might use those insights to cross-promote certain products in stores or ads, or to better target customers online. David Rose, who founded Ditto Labs in 2012, said one day his image-recognition software will enable consumers to “shop” their friends’ selfies, he said. Kraft didn’t respond to a request for comment.

Ditto Labs also offers advertisers a way to target specific users based on their photos posted on Twitter, though Mr. Rose said most advertisers are reluctant to do so because users might find it “creepy.”

Mr. Rose acknowledges that most people who upload photos don’t understand they could be scanned for marketing insights. He said photo-sharing services should do more to educate users and give them finer controls over how companies like his treat photos.

Beyond image recognition, some API partners employ a process called “caching,” meaning they download photos to their own servers. One of the more common uses of caching is to build a marketing campaign around photos uploaded by users and tagged with a specific hashtag.

The companies don’t mention caching in their privacy policies and they vary in how long developers can store photos on their servers. Tumblr, for example, restricts caching to three days while Instagram says “reasonable periods.”

Some developers have already overstepped the rules set forth by photo-sharing sites. Last month, Pinterest learned from a Wall Street Journal inquiry that Piqora, one of seven partners in its business API program, launched in May, was violating its image-use policy.

Piqora, a San Mateo, Calif., marketing analytics startup, collects photos into a graphical dashboard that help companies such as clothing and accessories maker Fossil Inc. track which of its own products and those of competing brands are most popular. This violated Pinterest’s rules, which restrict partners from using images from the site that were posted by anyone except their own clients.

After Pinterest learned about the violation, the company asked Piqora to discontinue the practice and plans to begin performing regular audits of its business partners, a spokesman for Pinterest said. Fossil didn’t respond to a request for comment.

Piqora co-founder and Chief Executive Sharad Verma says he has removed the ability to view competitors’ images in the dashboard. He also clarified his company’s cached photos policy from Instagram. Rather than keeping photos for an indefinite period of time, Mr. Verna said he will now delete photos from his servers within 120 days.

“We might be looking at doing away with caching and figuring out a new way to optimize our software,” Mr. Verma said.

作为Pinterest的忠实粉丝，topic非常让我着迷，其实题材也适合放在经管里的

56"->When we post photos or browse the information online, application software on websites track our preferences and share to companies for customized marketing. These days, Pinterest, a photograph social network, functions as a 'customer resource center' for sellers.


44"->Heavily addicted in various social networks to catch up with news, modern people seem to have little time for a daily life. Every year, a new star pops up on the network platform. Pinterest is latest popular graph media, with its users uprising fastly.  


1'05"->Pinterest is a graph media. How to use Pinterest: users 'Pin' their liked photos, sometimes along with texts, and then add to their own collection boards.

54"->
There are so many beautiful photos on a number of fancy resorts. Pinterest allows users to 'like'and 'follow' the publishers that share common inerests with them. It actually makes sense: you pin photos based on your interests! Apart from the simple pleasures of photo collections, the network also helps users to brainstorm ideas in life, for instance the wedding dresses, the kitchen displays etc.

Women account for 80% of Pinterest members.

1'30"-> Three advantages/features of Pinterest. Firstly, it's pure and ads-free. But the main income derives from referral fee, which companies pay for obtaining users preferrances. Secondly, it does not broadcast. Although add friends and share common interests on graphs, users simply collect photos wihtout broadcasting to everyone. Lastly, unlike Facebook or Twitter, it is against self-centered. The main topic is to discover interesting graphs rather than to promote and advertise oneself. However, there is still room for improvement.


1'20"-> Commercials on Pinterest: some photos are tagged with prices and linked to purchase sites. If users are interested, they can easily access to buy the products in graphs. Besides, the fancy photos also attract population and attention to users. This is especailly the case in the whole food sections.
It is hard to accept the fact that Pinterest stand out under the dominant online media Facebook and Twitter.


Obstacle 3‘46“->Digital media give away users data to allow companies to tailor marketing strategies--analzing customer preferences, product feedbacks, and targeting potential customers. Currently, API violation to users' privacy is not binded by any law.
Some media claimed that they have informed adequately that broadcast information might be exploited by commercials while others declined to comment. After realizing the violation, Pinterest ceased the use of certain process and limited its data access to business partners. Meanwhile, dashboards technologies are improving on the privacy protection.
