Have you guys been following this podcasting stuff? It's getting pretty big. Podcasting is basically just a fancy name for uploading audio files to the Internet so that users can download them and listen to them at their convenience.
Applications include classes, comedy clips, church sermons, dating personals, and news broadcasts. Obviously blogging is already being impacted as well.
Anyway, the reason I bring it up is that Apple just announced that its free iTunes software now supports podcasting - meaning that users can download podcast files to their computers and synch them with their iPod. The podcast directory in the latest iTunes will feature content from the BBC, ESPN, and other news channels.
To show you how mainstream this is getting, I just added an evangelist called John Malone to RIA today. When verifying he exists, I went to BibleStudy.net and saw a big podcasting button which would allow you to download his sermon.
