Thing #12 - Rollyo

I can see why people would find this useful - it is the internet's version of a federated search. I know I have a list of favourite sites already grouped by catagory and being able to search across these favourites without having to visit each individually would certainly save time. The only drawback I see is the lack of advance search capabilities. As soon as you combine sites you become restricted to lowest commonn denominator searching which reduces the power of your search. However, for initial browsing of a topic this would be extremely useful.
