Sharing the love of Facebook

Facebook wants investors to like it when it goes public later this week. But it's the users that are the lynchpin to its appeal.

SOUNDBITE: SARIE ERICKSON, FACEBOOK USER, (ENGLISH) SAYING:

"I can't go without it. No, I'm addicted to it, for sure. Yep."

SOUNDBITE: TRAVIS ROLLO, FACEBOOK USER, (ENGLISH) SAYING:

"I use Facebook about two or three times a day, mostly on my phone. I'm pretty addicted to it and I don't know if I could get by without it."

SOUNDBITE: ALEXEI TONKOSHKUROV, FACEBOOK USER, (ENGLISH) SAYING:

"I spend nearly two hours per day. I communicate with my friends around any countries."

According to comScore, the average user spends more than six hours a month on the site.

The key is something called stickiness, according to digital strategist and social media expert Peter Shankman:

SOUNDBITE: DIGITAL STRATEGIST AND SOCIAL MEDIA EXPERT, PETER SHANKMAN, (ENGLISH) SAYING:

"Facebook has a very large stickiness base. People come. They come back. They come back multiple times a day. That's what Facebook is counting on to drive the price of their IPO "

Facebook has been able to capitalize on the most basic human impulse to share things with friends- and keep them coming back. Jonah Peretti is the founder and CEO of Buzzfeed.com:

SOUNDBITE: JONAH PERETTI, FOUNDER AND CEO OF BUZZFEED.COM, CO-FOUNDER HUFFINGTON POST, (ENGLISH) SAYING:

"It's tapping into something human and basic that people want to do and have tried to do with e-mail and have tried to do with other services and haven't been able to do and it's actually solved that problem and I think that's why they're so successful."

The passionate addiction of its users is priceless. But if there were a price- it could be around $100 billion, the potential valuation of Facebook after it goes public.
