I have no idea who MrSapo is, but he/she/they have an interesting search interface. As Tara Calishain puts it, it’s not exactly a meta-search engine — more like a “meta-interface” site. But it’s pretty cool — you can run your search on multiple engines all in the same window. You can even run different types of searches — Basic, Images, Audio/Video, Academic, News, and Weblogs — there are over 80 search engines used!
