I took this from Kurzweil which looks like a direct quote from The Guardian but it was so exciting I had to quote it directly.

Blinkx is a new search engine that’s taking on Google. Launched today, it has been recording 6 million hits a day solely from word of mouth.
Blinkx doesn’t only search the web but simultaneously scours news sites, blogs, emails, attachments and your own hard disk. It does all this unobtrusively in the background until you pass your cursor over icons at the top or bottom of the page, when it reveals a digest of related sites as well as material from Word, Excel or PDF files. If you are working in a word processing document, it provides the same service.
And unlike Google, it uses artificial intelligence to rate stories, not page rankings.
