Free Podcasts at Open Culture: Informational Podcasts on Almost Everything
Free podcasts over at http://www.oculture.com/weblog/. (Actually, 99% of podcasts are free, but it's an adjective that never hurts.) The sheer volume of worthwhile, information podcasts listed on this Open Culture is amazing. I'm going to be spending a few hours just grabbing all the podcast feeds into my FeedDemon newsreader. Wish they had a big OPML file sitting over there. There are also good podcast recommendations in the comments sections.
