Which is better http://Myspace.com or http://tagged.com ?

Answer 1

Better in what way? Myspace has about a billion more members (more or less :-) ) but if you ask me tagged looks better.

Basically anything other than Myspace is just an imitation of Myspace. If you don't care about all the junk you get on Myspace, use that. If you want something a little more refined, with less users, use Tagged.
