My current favorites:
TWiT
DiggNation The latest episode actually made me snort soda through my nose at work. It's super-geeky and lightly obnoxious, but the bit about the sheepherder using wifi almost killed me.
Security Now
Sparkletack, which I haven't tried yet, but looks really interesting. It's history bits about San Francisco. I'll be listening to it during my commute in tomorrow.
