What's the best social networking websites I can join?

I'm already on Bebo, Faceparty %26amp; Facebook! I'd like to join a website where you can have lots of space to write about myself, interests etc free photo %26amp; video uploads with instant chat rooms. Facebook would be great if it had instant public chat but social interaction seems to be based around applications and not enough actual conversation!
