A quick few tests, I get Google.  Remember Magellan and AltaVista back in the 90s when your search would pull actual information sites rather than paid for commercial sites? I suppose that was as much a result of the percentage of actual web content that was non-commercial more than the algorithm of the search engine.  I think Yahoo wasn’t ever as much a search engine per se as a search of its own content directories but I may be wrong.

I get google as well. I remember Ask too, I used to use that.

Ask is still running.

Yeah, but I switched to google anyway.
