Looking for some good podcast. I just started subscribing to car talk, does anyone know of any other good podcast?

I like the sports podcasts and the Happy Tree Friends video podcasts.

Depends on what you like.

I listen to several

Ask a Ninja (video podcast)
Escape Pod (scifi stories)
Pseudopod (horror stories)
The Married Man Podcast (funny stuff about marrige, single and stuff)
The Instance (WOW stuff)
The Lost Podcast with Jan and Jack (Lost TV show)

many others.

There are so many out there it is hard to recommend just a few. As Carlton said it does depend on what you like.

I listen to Escape Pod and Pseudopod as well although I'm way behind.

I recently started listening to one called "The Race to '08" from CNN. It's a quick podcast (about 2 minutes that discusses real quick what is going on the presidential race.

Some others I listen to:
MacCast, TWIT (This week in Technology), Cranky Geeks, Boagworld (a web design podcast), and Skydive Radio.

Warning!: Podcasts can be addicting and if you listen in your car you may forget about those other crappy radio stations.

Exactly why I love my Sirius.
