RENEE MONTAGNE, HOST:
To the list of weird-sounding words of the digital age, like googling and tweeting, we can now add pinning. As in Pinterest. That's a website that's a bit like an online scrapbook or bulletin board. It's become one of the fastest-growing networking sites on the Internet.
NPR's Teresa Tomassoni examines the phenomena.
TERESA TOMASSONI, BYLINE: Last month, over 10 million unique visitors signed on to Pinterest. But some of them, like Billy Winburn, are still trying to get the hang of it. At an office in Alexandria, Virginia, Jennifer Folsom, who works a few desks away, is walking him through the process.
JENNIFER FOLSOM: So are you on there now? You have an account, right?
BILLY WINBURN: Mm-hmm.
FOLSOM: Are you following anyone?
(SOUNDBITE OF LAUGHTER)
WINBURN: No. People are following me. Actually, I'm following one or two people. But I don't know why.
TOMASSONI: But Winburn did find an architect on Pinterest.
WINBURN: So anything that he likes, I know I'll probably like as well.
WINBURN: But it could be something new, different and exciting.
TOMASSONI: And that's the point. Like-minded people find each other on Pinterest to share ideas. They pin things they find around the Web to their online pinboards. Wooden watches, wedding dresses, leather iPad cases. Then anyone that follows them can see what they've pinned, and vice versa. It's a place where you can save and organize things you'd otherwise have to tear out of a magazine or file away in your email. Folsom says this way you never lose track of them.
FOLSOM: It's all in the cloud, online, organized sort of wherever I am.
TOMASSONI: Like Folsom, most Pinterest users are women. And many of them, including Folsom's girlfriends, can't stop talking about it.
FOLSOM: We had this hilarious incident in the Jonathan Adler store where my friend said, I've seen that chair, I like it. And the other one said, I think I saw it on your Pinterest board. Wait, it's not pinned there. So she whips out her camera and she takes it, and she pins it, you know, as we're shopping.
TOMASSONI: On breaks during the workday, Folsom pins away too, using both her laptop and her Pinterest mobile app.
FOLSOM: It might be people's recipes I like or style I admire, whose organizational skills astound me, like this one right here.
(SOUNDBITE OF LAUGHTER)
TOMASSONI: She points to an immaculately organized pantry on her laptop. She found it scrolling through Pinterest's endless array of home decor photos. Then she pinned it to her home design bulletin board.
On her party time board, she pins a photo of Arnold Palmer Jell-O shots poured into lemon slices.
FOLSOM: That would be a great idea for a summer barbeque. Well, I don't know Jana Braswell, but I'm following her because she looks like she has a good time.
(SOUNDBITE OF LAUGHTER)
TOMASSONI: That sort of online interaction with people you don't know is an emerging trend in social media.
SUSAN ETLINGER: At first it was about how many friends do I have, how many can I get, how many groups can I join.
TOMASSONI: Susan Etlinger, an analyst from the Altimeter Group, says that's changing. Now people want to connect with others who share similar styles and interests.
ETLINGER: It doesn't necessarily mean that we're best friends or that we're even connected on Facebook or anywhere else, but it means that these are people that I learn from and that, you know, and who also maybe learn from me.
TOMASSONI: Etlinger says this shift is what's really fueling Pinterest's growth. Two years ago, when the site was launched, Pinterest hardly made a peep. Now that Facebook included a Pinterest app on its new timeline, the company has a potential audience of over 800 million people.
But, Etlinger says, it's worth watching to see if Pinterest holds on to its new users.
ETLINGER: Once people start to use it, then you really see whether they come back or not. So we really need to wait probably another, I would say, at least six months before we see whether this growth is sustainable.
TOMASSONI: One question is how Pinterest is making its money. The company declined an interview for this story. But their website offers this much: Entrepreneurs and venture capitalists have helped fund the company thus far, and advertisements may be in line for the future.
After all, it is one of the top five referrers of Web traffic to retailers.
Amy Rutherford runs a home furnishing boutique right above Jennifer Folsom's office in Alexandria.
AMY RUTHERFORD: I'm getting hits to my website from Pinterest, and that's actually increasing exponentially as, you know, as people are adopting Pinterest.
TOMASSONI: Hits haven't translated into sales yet. Still, she thinks the exposure is good. So every day Rutherford pins items from her store. And she recommends her customers use it too.
RUTHERFORD: A lot of people don't know what their style is, and when they use Pinterest, they can start pinning things that they see on blogs or on the site itself, and they go back and visit what they've pinned and they realize that they have a style.
TOMASSONI: Even if that style is a borrowed one.
