Well I don't have Facebook but I'd say Fanpop's better. It's fun to meet people with your same common interests! And Facebook to me just seems kinda creepy. I mean anyone can stalk you!
Fanpop!! I dnt have a Facebook account but I've seen my cousins go on and it's just plain boring!, I mean all Du do is chat there and here Du can RP and ask Fragen about your FAVE stuff and all that..
Facebook is in a little bit of a "crisis" over a stupid page somebody made over a Monat Vor and 95% of the people are butthurt about it, so I'd say Fanpop.
