I’ve been listening to The Nerdist podcast a lot lately. Mostly pop-culture stuff with a heavy slant toward the nerd/geek/fandom crowd. They get good guests–Nathan Fillion, the *Community *cast (individually), Robert Kirkman (creator of The Walking Dead), Adam Savage from Mythbusters, Bill Maher, Craig Ferguson, Simon Pegg–to name a few. The show definitely lives up to its name, but the main host, Chris Hardwick, is an experienced entertainer/performer and he keeps things rolling.
