SocialCashed: How many users will Facebook have by the end of '09?

Facebook recently went meteoric in the way of reaching 150mm users. For the past few months, they’ve been adding 10mm+ active users and there’s no sign that this will slow down anytime soon.

In a recent interview with Tech Crunch’s Michael Arrington, Facebook’s COO Sheryl Sandberg shared that they’ll soon be announcing a new functionality to the platform, allowing users to add more friends than you could ever imagine. This will probably add even more digits to their total number of users, and we’re curious to see what kind of numbers they’ll reach as the year progresses.

One interesting thing about Facebook’s growth is that most of it has come from outside of the US. As pointed out by our friend Justin Smith at InsideFacebook, some countries have seen well over 1000% growth in recent months. At Socialcash, we’re focusing 100% of our time on Facebook and believe that the Platform will continue to grow around the world.

I asked around for people’s guesses on what they thought those numbers would look like by the end of 2009, and below are their predictions. Whoever comes closest, at the end of the year, will get a fun prize!

What’s your guess? Stay tuned…
