Do any of the contributors to the Atheist on Youtube community ever come on here?
First, "here" is still quite new and is also small in membership. With the rate at which the membership is growing, I would hazard a guess that it won't be long before it becomes a venue worth considering by them as a possible way to "spread the word". In the meantime, just sit back and enjoy the site.
I have my doubts, oweing mainly to the name of the site alone. Atheists and Agnostic just do not mix. Ironic if you ask me, for a community that suposedly promotes free thinking.
An interesting side note, I just tried to go to atheist.com (for the heck of it) and my security suite (Vipre) blocked the site from loading.
