I personally subscribe to the "Your actions in the story make you who you are" idea. An interesting backstory is great for storytelling (and goes great in a place like here) but I've never been satisfied with my RP being me telling people about the things I've done.
Other than that, look around! See what people are up to, try and find folks who you think will mesh with you. It's a big world out there.
