Add feedburner support

I really appreciate the easy tie-in with Google Analytics, but that doesn't tell the whole story when I want to find out how my posterous site is doing. Not everyone that visits my site will sign up for Posterous to add it to their favorites, some will just subscribe via RSS.

Feedburner support would be great, because it would allow me to see how many people are subscribed via RSS, and see how many people are only reading the feed -vs- how many are clicking through to the site.
