I've used NetNewsWire as my RSS reader on the Mac for years. It's the best program of its kind, in my opinion. And now it no longer costs money. I sat for lunch with developer Brent Simmons and his wife Sheila a few years ago, and he is not only a smart programmer, but a nice guy.
If you read a lot of websites and blogs and would like to get the latest without constantly hopping from site to site, RSS is the way to go, and NetNewsWire is the way to get it if you have a Mac. Go download it.
