HubDog

I'm using HubDog from some time, and I'm quite happy with it.
It delivers a sort of RSS feed reader, with a good user interface, it's stable, and it can consume also audio/video *casts.

Hundog is "hubdog - centric", in the sense that you must have an HubDog account to have it working, and the list of your feeds is (actually it "can be") shared with others. And this is both a bad and a good thing.
A bad thing because maybe you're not happy to have HubDog know about your chisen feeds - a good one because you can search between other HubDog users feeds, thus discovering new interesting feeds you didn't know about.

Any way, HubDog is now at the 2.0 release. Link: http://www.hubdog.com/
