One of the great things about OS X (aside from all of the Unix goodness underneath it and the gorgeous surface) is the cool software that is being produced for it. A great little application is NetNewsWire Lite. It is a freeware RSS reader from Brent Simmons of Ranchero Software and it's one of the tools that I've added to my dock. One of the neat things about it is that it works in a similar way to Mail.app in that new articles show up with a little red square with the number of updated articles. So now instead of going back to sites to see when things are updated I just have to look in the dock. The upcoming Pro version will feature some editing capabilities... that could be cool.
