Free RSS reader Vienna

It's free, it's open source, and it's in beta. Vienna is a pretty sharp little RSS/Atom reader. I put it up against NetNewsWire, and it held up pretty well. Despite some strangeness involving dates, I actually like parts of Vienna better than NNW. For one thing, there are already three handy  Smart Folders set up for you: Marked Articles, Today's Articles (the one I had date issues with), and Unread Articles. Once I set it up to operate pretty much the same way NNW does, the only difference was a simpler interface in Vienna, a brushed metal UI, and less resource hogging. Hm. This Vienna thing is pretty cool... The full release is supposed to go live before the end of the year, so I guess it will be a happy holiday for the automated webomatic...
