• Feedblitz allows one to add rating widgets (feed rating system) along with the feed which makes the user to rate your feeds.

Feedburner is also equally good and the service is totally free. Even it has been claimed that you can use feedburner in alliance with feedblitz but I am not sure about the feature. Its all now in the hands of readers to explore more and make the most out of the two wonderful services.
