This is a site that does exactly what you think it would do.  Rotates insightful atheist quotes daily.  There is also the feature to submit your own quotes that are reviewed and added daily.  There will be more and more features added as time goes on and as I have time.  Please post any suggestions/criticismts you may have in the comments.

Keep in mind that atheist quotes need not come from atheists, as they often don't.  This site is more to promote the acceptance of atheist thoughts and maybe challenge someone's belief.  Religion in itsef is a fascinating thing.
