I just setup a FeedBurner feed for Media Grease which you can access at: http://feeds.feedburner.com/mediagrease
Using FeedBurner helps in a couple ways. When people and bots check your feed, they are hitting FeedBurner’s servers and not yours. FeedBurner has a number of feed customization options that aren’t built into WordPress, like the ability to have one feed address for RSS, RSS2 and Atom.
There is a little more work involved in getting your WordPres site to direct people to the FeedBurner feeds instead of the built in ones. For that purpose I’m using a WordPress plugin called Feed Locations.
