Maybe the hosts of the show could look at the discussions in these forums, pick out interesting recurrent topics and discuss them on the show. I think this should make the show more interesting. For example look at the following discussions:
General Discussion
"If there was a God, he is EVIL"
Andrew wrote there:
"Nobody asks to be born, so we are forced to exist and try to survive even though it is futile to even try."
Recently there was a similar topic here:
General Discussion
"What to tell an 8 year old about death."
So how about choosing a topic like that and talk about it on the show? The theme for the show could have a catchy title like this:
"Is it "evil" to have children?"
Or maybe the hosts of the show could have a live talk with the members of 'The Voluntary Human Extinction Movement' ( http://vhemt.org/ ). And discuss the issue of having children from an atheistic point of view.
I think that choosing interesting controversial topics like genetic modification, designer babies, artificial intelligence and sentient rights, animal rights and so on and talk about them should spice things up a bit and attract more followers to Atheist Experience.
