Alertbear is described as "the free Windows RSS reader that doesn't think you should read feeds like email," agreed. Alertbear is a nice little free feed reader for Windows that lives in your system tray and pops up a "stack" of news reminiscent of IM notification boxes when new feed items come in. It has some nice features, like color-coded categories, mousewheel navigation, and feed auto-discovery, but otherwise keeps things simple.
