It looks like Yahoo is trying to read people minds with its new Instant Search feature (see the News.com story, "Yahoo debuts beta of Instant Search" - http://www.techrepublic.com/2100-3513_11-5867118.html).
This feature reminds me of Word's AutoComplete option, except for Yahoo's results appear in a "speech bubble" under the search box. Cute. Some people will love it, and others will hate it. I played around with it for a little while, and it didn't impress me with its inability to detect "techrepublic" (read = loss of brownie points). Quite frankly, I think it could get annoying. If you've ever had someone constantly try to finish your sentences, you'll know what I mean.
