Apple's official endorsment of podcasting is something I was not aware of. They have integrated podcast subscriptions into iTunes and are also promoting garageband as the ideal tool for podcast creation! This is good news to all podcasters -and listeners too!
UPDATE: Also read Podcasting Made Easy: FeedBurner support for iTunes, Odeo, and Yahoo Media RSS. I get the feeling that this move by Apple and others will actually make podcasting available to evryone.
