Facebook, like all social networks start off really good... but as their popularity grows... it starts to get inundated with crap...
I mean, don't get me wrong... I play the games (because I don't have anything to do
) but for me the best part is keeping in touch with friends... I don't like to use MSN/AIM too often... I don't know why but I just don't really like to use them.
Also, facebook keeps me in touch with all the people I first talked to here and care for deeply, who have decided to leave MTF forever.
