How Many Weeks Until Facebook is #1?

Facebook announced today that they have 41 million active users up 70% since they opened their platform up to folks like me just a few months ago.  My last number from MySpace has them still holding a dwindling lead of 52 million active users.  Just seems like the change in leadership position is inevitable at this point.

CEO Mark’s chess move to open his platform and embrace the development community might well have been the checkmate in this current game of social network battles.  Bravo.
