I would say Facebook over Twitter and Netlog, simply for the fact i have no clue what netlog is..
Facebook is a series of stalkernes, yes, but Twitter is
"3:04 iim On Da Shiita #BrownsInDaSupaBowl"
"3:06 BoouT 2 Eaat Sum Gruub #STUFFIN"
"3:14 Watchiin Dat Fuutbal #DEMCOLTS"
it just gets ridiculous after a certain point and time.
