Anyone else using it? what do you guys think? I think the idea is good, the groups aspect makes so much more sense than sharing everything with everyone on facebook... with my little cousins on facebook its like i barely add much because its gotta all be censored, or there can't be drunken debauchery in the pictures... I think it'll do well as long as they keep this buzz going and have people move over... let me know if anyone wants an invite...
