I tend to be a 'drifter' when it comes to social networking sites. For a while it'll be Facebook, or Blockles, or I'll be on Spogg.com, then I come back here.
I've realized that I don't realize that I miss atheist solidarity and companionship until I come back and experience it again.
I've recently had the pleasure of conversing with a fellow atheist "irl" and just the fact that I can call someone my "atheist buddy" in a sea of the religious makes me smile. The feeling of having some small but meaningful connection with someone else who has taken off the blinders is wonderful.
So back to social networking sites: Atheist Nexus, thanks for providing a safe space for the logical people of the world to come for a little sanity.
