I think this is a decent logo, but in my opinion it is very technology/msn esk.
if this is a social network for lifestyle/health/cosmetics etc, something more organic and beautiful may be in order.
the shiny generic avatar icon is typical of the anonymous software user icon.
This logo has a professional finish, but this is not the logo of a unique brand. And, fair enough, many domain first, development second sites are not trying to create a strong brand, that is not the play.
I hope this feedback helps, and if you decide to keep the logo, I think that's OK.
