Well, so far, I haven't had any luck in getting a podcast to work. The last three "test" posts tried three different strategies. I've uploaded a silly little test file (in .ogg format) to the Internet Archive, and have now tried the embedded link route, then tried using the Blogger method of enclosure links and also tried using an embedded Flash Player. No luck so far. If anyone has any clues, please let me know. I'll keep plugging away in the meantime.
