Yahoo! has been beta testing their personalized search named My Yahoo! Search. It comes on the heels of Amazon's release of a9 and AskJeeves release of MyJeeves. Right now I am using My Yahoo! Search more than the other two because I use a few of the other Yahoo! properties (maps, My Yahoo!, finance, and mail). a9 looks good especially since it uses Google for its web searches -- and also because it has links into Amazon, Google images, and IMDb. I never really liked AskJeeves (its bot is a bit rude and its search results not as good as Inktomi [Yahoo!] nor Google), so MyJeeves really does not appeal to me.
