FeedFlare came about after the FeedBurner folks sat around thinking about "the importance of the feed item and the ability to leverage the structure of the feed to build a bridge between web services and the content item." Basically, this means you can select some stuff that will appear in the feed footer that makes it easier to see items/perform actions which are becoming more and more integrated with the whole blogging experience. The first release of FeedFlare includes communication between your feed and email actions, del.icio.us and Technorati links, and Creative Commons, as well as comment counts for WordPress feeds.
