I happened across mention today of Filangy today. It seems to be a personal web search engine, though it's invite-only, so I don't really know what it's about. It's based on Nutch, which is an open-source web search engine.
I hadn't heard of either of these before, and they sound interesting, though oddly named. In particular, Filangy is pronounced the same as the last name of Phoebe's alter ego on Friends, Regina Phalange. I guess all the good names really are taken.
