Yahoo Mindset Beta

Mindset is a beta release from the Yahoo Research Labs. They are calling it intent driven search.

It marks each search result with a rating on a scale which defines the nature of the content - commercial or academic. Also, it provides the user with a slider on top of the search results. You can use the slider to define your preference on the commercial-academic scale. Based upon your choice, Mindset rearranges the search results accordingly.

I tried a search for the keyword "routers". You can see the results here. Now if you move the slider to the shopping side, results like Amazon.com and tigerdirect.com move to the top. On the other hand, if I move the slider towards research then the top results are a few RFCs and Wikipedia.
