Facebook is a really good way to stalk people.
The site was the number 1 time waster until May 5, 2007 when The Wiki Fire took over.
Knox College got facebook in the spring of 2005 and within days it seems everyone was on it. If you look at some people's user ID's in their profile URLs, you can tell how soon they joined facebook. For example, Graham Troyer-Joy's profile can be found at:
http://knox.facebook.com/profile.php?id=62600106
...indicating that he was the 106th person to join the site.
