I don't really see a use for Rollyo! I suppose if I was doing a lot of research on a limited topic I might be able to put one of these search bars on my toolbar for frequent use. However, most of my searches are all over the place, and on a variety of topics. I guess the concept is that someone else has already done a portion of the work for you. Because they have already selected certain sites they find credible for that specific keyword, it may prevent you from going to arbitrary sites generated by a generic search engine. I guess my skepticism come in because every individual has their own thoughts on what is relevant or a credible page to use as a site resource. Below is a copy of the Rollyo I created with the keyword Physiology. I chose several academic and national organizations to search.
