How they count their numbers is the big question. They constantly bombard me with emails and I don't have the time to waste being on their service. A friend of mine constantly puts them in his spam folder but they must revolve the servers, because he hasn't been on facebook for over 3 years yet keeps getting mail. I also know all kinds of people who can't ever remember the log in that they used. That coupled with IPO question I wouldn't trust anything coming out of facebook.
