If you're a fan of the RSS blog reader built into Internet Explorer 7, you need this program. It adds two quite useful new features--the ability to read all of your feeds from a single location, instead of having to read a feed at a time. This is especially useful for people like me who subscribe to dozens of feeds. Rather than spending your time clicking from feed to feed, they're all in a single location. And because IE 7's feed reader has exceptionally good filtering, sorting, and searching, it's still easy to find a specific blog item. Also useful is that the program will alert you when your favorite feeds have new content.
Note that this program works for Internet Explorer in Windows XP as well as the version built into Windows Vista, so even XP users will be happy with it. However, it does not work with IE 8.
