Adding Feedburner RSS
As an alternative to the included WordPress RSS feed, you can also incorporate an RSS feed from Feedburner.
To do this all you have to do is create a Feedburner account, “burn a feed” there using the included RSS feed URL — which will look like http://yourdomain.com/blog/index.php/feed/ — then create a new feed URL that you’ll use in this theme’s configuration. That simple, or at least I hope it is for you.
