I just finished reading Podcasting for Dummies. A lot of it was both interesting and helpful. I've just reedited (or, if you prefer, digitally remastered) my first two podcasts and posted them to a free account at PodOMatic. OurMedia is sometimes a little unreliable when I try to upload, and I'm not sure how much bandwidth they offer. However, PodOMatic messes with the ID3 tags when I upload, so we'll see how long my patience lasts with them (I know, I just want it all, huh?).
I've finished student teaching and plan on podcasting sometime this week, so keep your ears open for episode 3.
