Very interesting. Tried a few searches (“josh bancroft”, psp, tinyscreenfuls, “creative zen micro”) which should have turned up hits for TinyPodcast, but got pretty sparse results. Though it did find some old audio files I posted on GadgetFamily.org way back when.
You can submit the RSS feed of your podcast to be indexed. I dropped in the feed for TinyPodcast – let’s see if it shows up soon.
Want an interesting search to try? How about “mashup”.
