I'm afraid I have to agree about the guest interviews slipping in quality. Considering Chris has so much free time, why is it so hard to do some simple preparation for interviews? Seriously, just use google and jot some things down on a notepad, then ASK decent questions!
I know I've probably mentioned it before, but I'm a fan of podcasts, two networks in particular, Nerdist and Smodcast. I've been listening to Nerdist a lot lately, and they have the most amazing guests on, and the interviews are (largely) brilliant! The host, Chris Hardwick, actually asks interesting questions to get the ball rolling, and then the interview develops from there. All you need is some good questions to get the guest to open up a bit!
If you ask dull questions, you don't give the guest anywhere to go.

I'd urge everyone to go listen to some podcasts from

www.nerdist.com and let me know what you think
