I came across this great site from Guy Kawasaki http://alltop.com/ which helps you explore your passions by collecting stories from “all the top” sites on the web. These collections are aggregated into individual Alltop sites based on topics such as environment, photography, celebrity gossip, fashion, gaming, sports and politics which are updated every 10 minutes. At each Alltop site they display the latest five stories from thirty or more sites on a single page — they call this “single-page aggregation.”
They claim to have created the “digital magazine rack” of the Internet where they create starting points not destinations to enhance your online reading by both displaying stories from the sites that you’re already visiting and helping you discover sites that you didn’t know existed.

They have a goal of the “cessation of Internet stagnation” which seems like a lofty intent but I think it works very well and goes a long way to start helping people through the quagmire of subject related sites on the net - this is especially relevant if like me you do not focus only on the feeds you have in your reader, but you want to read something different it is perfect.
