12. Rollyo

I can see this having potential uses, especially the example one for quotes (since I have done many searches for quotes for our roster, where many of the same sites would show up each time).
It took me a little thought to work out the difference to Google, though. Usually a Google search provides accurate enough results from pages that I trust within the first page that I don't really need to have it narrowed down further.
It does seem useful if I did have a collection of sites that I searches all the time; but I don't have enough to make it worth my time setting up a rollyo for the few sites I do search. Still I might revisit this sometime.
