I recently switched to Blogbridge to follow my blogs and it's definitely become my favorite. It's really customizable and looks good, with thumnails and embedded images. I really appreciated the fact that it automatically picks up feeds just from the web address. I hate rss readers where you have to enter the feed url, because if you get it wrong it won't correct it for you. Blogbridge also seems to be the only one to allow you to set tags and ratings, something I've gotten totally addicted to, thanks to the web 2.0 craze.On the downside I almost gave up installing Blogbridge. The installation process was just really long and repetitive.
Pros: Customizable
Picks up feeds from address
Cool rating system and tags
Cons: Lengthy installing process
