I'm going to use this space to say how much I miss Bobby and Cort's movie commentaries. I listened to all of them and they were all super fun and interesting.
It's not local unless you're reading this in San Francisco, but I've been enjoying the Boars, Gore, and Swords podcast, in which two comedian-nerds (Red Scott and Ivan Hernandez) and guests riff on episodes of Game of Thrones. Of all the GoT podcasts I've tried, this one stands out because they're actually funny and because they're not just repeating variations on "I'm confused and angry because the tee-vee show isn't an exact match of the book." They're also good about avoiding spoilers since they've only read as far in the books as the tee-vee show has gone (give or take a few long-winded descriptions of medievalesque meals).
C&B: With all the people involved, I think Nerdfight is more of an event podcast than a regular show. But I know they're recording a new one this weekend at WonderNW. http://chroniclesofthenerds.com/nerdfight/
Also, what happened to Nerd Fight?
