Eatfeed is a self-described 'barebones' feed reader "born out of frustration from the brokenness of programs like Liferea and RSSOwl." Which, lets be fair, are pretty sucky.
Whilst there are some great AdobeAir based desktop RSS readers, people looking for a more native solution should try out Eatfeed.
It's by no means feature busting; it won't let you auto-mark items read or sync with your Google Reader account but it will let you add feeds, get updates and read items without leaving the app.
