A while back, I posted a link to a site that lets you test search tools against one another: Webmasterbrain. This site lets you search in three search engines simultaneously and vote for which one executed the best search. In this "blind tasting," it's evident that Google doesn't always win.
There's another new search site on the block that I've been trying out: Clusty. Clusty is interesting cause it also automatically clusters your search into relevant related groups ("Clusty," geddit?).
It works pretty well. It will give you second thoughts about Google's dominance. Check it out.
