Considering the top social network sites, none of the domain names represent the word social, maybe two or three of them signify actions that revolve around the act of socialising. Apart from promotional work to gain registrations, they all work the same but some more popular then others. If you thought the domain name gave you an advantage and you had an unlimited choice of names what would you call your social site and why?
Maybe I didn't explain myself very well... I meant would you go for something like (silly examples) BFF.com which everyone knows what that is? or would you chose a social word.com or even an action world tagalong.com Opinions will differ, yes... just trying to get a general consensus
