Only two. Pipes Magazine, and The Mortification of Spin, a theological podcast w/ 3 snarky and slightly cynical orthodox Presbyterians fightin' the good fight against all sorts of theological shenanigans.
I used to listen to a few others, World Soccer Daily (don't think it's around anymore), and various fly fishing podcasts, but in they fly fishing world, everyone is an expert and out to one-up each other, and it drives me crazy. Plus I felt like the whole point was to get me to buy more $700+ fly rods so I could keep up w/ the "latest techniques".
