Have you ever convinced a religious person to become atheistic? How did you do this? How long did it take? Were the people in some sort of life crisis, or were they just living along?
This is probably a quite difficult task of persuasion. So stories how people were successful at it could be very interesting to improve ones' persuasion abilities.
Relatedly, it might be interesting to know what religious groups have gathered on techniques to convert people to their religion - are there some manuals/techniques floating around?
I was told once that things I said in english class helped convert a friend of mine to atheism, but this was so long ago that I can't really remember what I said. In terms of my own experiences of giving up beliefs I've had, a key factor is readability and honesty in presentation. Things like Yvain's non-libertarian faq are fun to read and seriously strive to address the viewpoints that I formerly held as a libertarian. It didn't make fun of libertarianism, but allowed it to reveal its own silliness by talking about it.
