You are only a couch and some beer away from being the next Diggnation :P Seriously though, have you thought about instead of having a few guests talking about stories, make it open mic so everyone listening to the show could also participate, open mic style? That could be fun.
I'm also writing a tool that helps podcasters organize sound clips and coordinate broadcasting with multiple guests: https://github.com/jiakeliu/Cobra
Please excuse the svn to git transfer mess, but maybe this tool would come in handy one day.
By associating speakers with HN accounts, you could filter out below a certain karma. Not to make it a clique, but more to just stop junk callers to some extent. Not too sure what I think of the open concept, but thought I should point it out.

Best of luck!
