Monitoring RSS feeds

There was something about this here a while ago, and while I’m not sure this will work ‘off the shelf’ due to how WP creates the feed (that ‘other’ blogging tool is used as the example), it’s certainly looks interesting.

“FeedBurner enhances your current RSS or Atom feeds in a variety of ways that YOU control, while simultaneously providing personalized usage and trend statistics that describe how your feed is being used.”
I’ve literally just found it, but I’ll be trying to install it later.
(Edit: Ads may well be involved….)
