Feedburner is a service that, although we’ve long thought Google would kill it, still exists. I’m starting to wonder why at this point! Google isn’t doing anything with it, and hasn’t for a while. That being said, I think this is the smallest of the lists I’ve compiled so far.
Feedcat.net Feedcat does most of what Feedburner does, without the email delivery.
Feedblitz Feedblitz isn’t free, and doesn’t even have a free tier.
Feedsnap is probably the one I’ll use if I ever end up using a service for my feeds again, (which I might when I switch away from Wordpress.)
Feedio This service gives you a profile page to let readers subscribe to your feed from, as a subscriber, I’d rather do it straight from the feed.
Feedpress A service that charges $4 per month for feed analytics, and also offers podcast hosting. They do offer a 14 day trial.
