Accident. I was googling atheist something..don't remember now and this site came up.
I saw ads on FB...and learned how to post them there myself.
First found Ag via an ad on FaceBook when it first launched. Not sure what you mean by "work". It's a social site that is mostly free of religious BS. In that sense, it works. As to therefore also being a site of openmindedness, intelligence, and tolerance... not so much. Those seem to be decreasing as membership increases.
