Technorati

Had a look at this site. Visually it's a bit busy and I'm not sure the quality of the material it retrieves is any better than you'd get doing a google search - but it does search across blogs, images, sites etc and generates and presents search results from the one home page, which Google doesn't do. But on the whole I prefer the uncluttered look of Google. I see this one as being more useful for hobbies, pop culture searches - that kind of thing.
