RSS Aggregators: Which Should I Use?

RSS Feed-readers are a hassle-free way to keep yourself updated.  They allow you to receive updates on all of your favorite sites, blogs, etc., without revisiting each site individually.  It's like designing your own magazine that is constantly being updated! 

I signed up for a few online-based feed readers and briefly analyzed them..
