One of the tips coming out of WordCamp Toronto was to use a service like FeedBurner for your sites feeds. I have covered a few times on this site how RSS feeds work, check out the related posts below. What FeedBurner does is redirect all the feeds through FeedBurner, which allows the feed owner to track useful stats like the number of subscribers and the number of posts are being read. So if you happen to be a subscriber try picking up the new feed so I know you are out there.
