Cem has numbers about the real size of Facebook - astonishing!

* Facebook now has more than 42 million active users (double the number one year ago when it opened up registration and growing at more than 200,000 per day since January)

* More than half of Facebook users are outside of college (85 percent of US college students still use Facebook)

* More than half of active users return daily (users spend an average of 20 minutes on the site per day)

* Facebook is the top photo sharing application on the Web

* There are more than 6 million active user groups on the site

* More than 80% of Facebook members have used at least one application built on the facebook Platform

I find Facebook way to difficult to use and navigate. I have hardly seen a site that is so confusing. On the other hand it's really fast making 'confused clicks' easier to stomach.
