For those that might be interested in a little bit of my own habits of podcast listening, I managed to figure out how create new syndicated feed with LJ. The first two I created are as follows:
podcastwho - The host of this Doctor Who-related podcast is based in Charlottesville, Virginia. The XML comes via his blogspot site.
hshearer_leshow - Harry Shearer's (voice of many Simpsons characters and also of This is Spinal Tap fame among other things) Le Show which can be heard on many NPR stations throughout the country. This has been available via podcast for some time. KCRW provided the XML for this one, so now you can hear Harry's ramblings and various voice parodies in mp3 form.
That's about it...for now...
