To post my podcast I used Tumblr.
I tried Richardson's suggestions, but my podcast guests had other commitments so we went with the one that Tom uses all the time. If you listen to my podcast, and I hope you do, you'll hear some savvy young folks talk about the technology they use and some of the ways they see media evolving. At the very end of the piece they give a plug for their videogame website. Or check it out @ quiksave.net
