^ That's the thing. I use Myspace to play the apps. I don't add apps on my facebook (except for that Yearbook one) coz it just makes it all spammy & if I wanted spam, I'd have used Myspace.
I have 2 facebooks. One for real life friends and family, and the other for playing Mafia Wars. I have over 3k friends on that account. That is also the account I use for staying in touch with online friends.
if have mutual friends then i would think of adding(atleast 10 mutual friends).. If not, NO!! I wouldn recommend too!!
