There’s been a bunch of buzz over the past 24 hours about a statement made by Mark Zuckerberg this week at the Web 2.0 Summit. As Saul Hansell wrote in the New York Times on Thursday, “I would expect that next year, people will share twice as much information as they share this year, and next year, they will be sharing twice as much as they did the year before.”

If you’ve been at a conference where someone from Facebook was speaking in the past year, then you’ve heard repeatedly about how Facebook is all about sharing. The idea is simple but powerful. Users continue to post more photos, upload more videos, write more status updates, connect with more friends, and ultimately are spending more time sharing their lives online.

While people aren’t living online, Facebook and other social utilities have become an integral part of the digital lifestyle. If Facebook’s success relies on the Zuckerberg law, the company definitely needs to focus on making sure they are the easiest platform for sharing information with all your friends. Fortunately for Facebook, the company is arguably the best way to share information among friends.

As long as Facebook keeps attracting users and remains to have the most accurate representation of the global social graph, they will remain to be the best place for sharing information. If the Zuckerberg law holds true that means Facebook is going to have a lot of information to store over the next few years. Now all the company needs to do is figure out the best ways to monetize that data.
