Adding FeedBurner support

Out of curiousity of what it actually does and what additional benefits it provides, I've set up "The Bungling Sys Admin" in FeedBurner. I haven't figured out why people use this service, but curiosity killed the cat. Hopefully it won't "break" my blog. Feel free to comment about your experiences with FeedBurner, why you use it or don't use it, and if it made anything go awry with this blog.
