I just came across three search engines that are finding the innovative edge of search engine technology. Thank you to David Berkowitz from MediaPost's search insider:
Goshme - aggregates hundreds of search engines and recommends the best for your search.
Like - Beyond cool and one of the most interesting ideas I've seen in a long time. The site does visual search for shoppers. See a watch on the hand of your favorite celebrity, search for it and others like it on the web. Want to change the color or looking for a specific price, no problem. Easy to use, very powerful.
Indeed - Metasearch engine dedicated to job hunters. Easy to use, great results.
