My endo review is up at Macworld. As I say in the review, it's "a good choice for feed addicts with a lot of subscriptions, especially those who are also bloggers or who download lots of media files." In fact, it's replaced NetNewsWire 2.0 as my feed reader of choice--largely due to its ability to track comments I make on Flickr, delicious integration, and the like. However, I have yet to run NNW 2.1, and I expect it to be chock full of great new features. In any case, it's amazing to me that the Mac has--and has had--the best feed readers available on the market.
