Ask.com has been hard at work improving their engine ever since they let Jeeves go. They have quite a few TV ads promoting it, but he coolest thing I’ve seen so far is a great, interactive demo on what’s new and how to use Ask.com. It’s all about spending less time searching and more time finding. http://searchtools.ask.com/
I think I’ll change my Firefox search box to Ask now to give it a go myself.
