The name "Podcasting" has always sounded a little trite to me. It gets it's root obviously from the iPod, but why imply a limit to a particular platform? There is obviously a bunch of confusion out there right now as many people have been posting "but it's not just for the iPod, it'll work with other players too". So why name the "idea" podcasting, and the apps "iPodder" or the directory "iPodder.org"? It just confuses the issue.
I like the meme that's floating around the 'sphere right now of renaming as Mobcasting. As in mobile. All digital audio players can take play the podcasting content - don't artificially limit the promise of an idea with a bad name.
Anyhow, those ubiquitous cell phones are gonna be the platform this tech needs to hit.
