The best RSS reader I've used so far is newsfire on the mac.
Just last night we tried xtorrent, a bittorrent program written by the same guy. It is definitely up to the standard of newsfire, great interface and the search works too!
Xtorrent 1.1 was just released so it might be a good time to buy.
I recall reading about this when it first came out and getting all excited about its fantastic UI design and then wishing I owned a Mac. I'm still occasionally tempted to do something about that impulse... now is one of those times!1: Comment Link
