"Great stuff. About time we had one of these, and you're the right guys. I presume that between you, you can sort out XMLing a syndication feed so people get it automatically?
So, I like it - but I presume you're looking for suggestions rather than praise, so here are some half-formed thoughts, written while listening.
* setting: listener instinctively wonders where it is. thoughts: go abstract (inobtrusive music underneath)? or set it somewhere (a pub, occasional reference to getting another couple fo drinks)?
* play up distinction between "characters" - "so Fathers 4 Justice is a branch of MI5 now, is it?" very good, so why not play up the sceptical one vs speculative one or scurrilous one vs cautious one dynamic?
* listener also doesn't know how long it is - consider silly stings (ding the bell for the PR coup of Leo, honk a horn for the imminent demise of Ming,etc?)
* establishing and consolidating nicknames (eg Basher Davis) a nice hook
Good luck with it all!"
