Even though some folks like Dave Winer criticize Feedburner for "locking people in", I continue to find their service to be a valuable resource for podcasting. They've added functionality that properly tags RSS feeds for iTunes, which will insure that my podcast feeds have the proper elements and a nice image when they show up in the iTunes software. It's a pity that Apple didn't build this option in for podcast producers.

They allow you to add a category, subcategory, description and image url to your feed. This service is available to people who utilize Feedburner's Smart Cast service to power their podcast feeds. You can read more about it here.
