RSS Reader for Mac - NetNewsWire now no longer is a for pay version and a Lite version, but a completely free version. Version 3.1 is available for download here.

I've been a Google Reader fan since the new version came out a couple of years back... I'm definately going to give NNW a shot again as I did used to use it back in the old days when I had a PowerBook. Via 50 Leaves.
