Rollyo

Rollyo is a perfect example of 2.0 technology because it is customizable. My only experience with something similar is using advanced preferences in Google to include only certain domains in search results. Rollyo allows the user to cover only certain websites, divided by subject, in search results. These subjects are preset or customizable. For example, I used the key word "cinnamon" and searched using three different preset subject groupings: Health, Recipes, Celebrity Gossip. As you can imagine, the results were very different! An interesting search tool.
