Kartoo

Take the worst from metasearch engines like Vivisimo, the presentation aspects from something like RDFViz, implement it in an appallingly slow Flash interface (or a broken HTML one) and you have Kartoo. Initially, I was pretty impressed with this little flash bestie but it's slower and more cumbersome to use than Google and provides less information per screen than any search engine. If you are going to show what's related you need more information displayed than a tradition search engine not less. It also does literal words and not concepts. Also, the size of the balls and some of the other graphical qualities seem to be meaningless.
