I wish that he would incorporate more science like Dawkins and Harris often do. He'll say "I don't know" - which is perfectly fine and sometimes the best course of action, but there are sometimes answers or lines of scientific inquiry that he misses out on.

I can't really fault him on that. His background is in IT, not scientific research like Dawkins. Likewise Harris was, I believe, trained in neuroscience. Dillahunty is very scrupulous about not claiming knowledge he doesn't actually have. Instead he's focused on addressing the beliefs people claim and examining them.

And he tends to give backwards idiots too much say and then will explode on them. Entertaining, but not really highbrow discussion.

I believe that's a deliberate strategy on his part.
