Feedburner's Feed Awareness API (read this article at Burning Questions also), allows developers to integrate feed stats to their applications. It gets even better if the feed you are using is a Feedburner "PRO" account. Then you can have views and clicks per item.
Here (look down the page, where this blog is syndicated) is a small example of using the API together with MagpieRSS from PHP. Notice the "views" and "clicks"? They are read using the Awareness API.
The code for the example can be downloaded here: fb_awareness_api_demo.phps.
UPDATE 2005-10-27: I put together a page with all my FeedBurner related code
