If you haven’t tried it yet check out Microsoft’s experimental new search front end Tafiti – http://www.tafiti.com.

It’s based on Microsoft’s new SilverLight technology, their competitor to Flash. It uses a cool desktop metaphor where you can spin through different kinds of results, drag and drop them into piles which you can label and share with your friends.

Although it might seem gimmicky and not particularly useful at first glance, it is actually quite innovative and and a lot of fun to use. It’s a great showcase for SilverLight but it’s interesting to contrast how Apple are doing a lot of work in bringing metaphors such as stacks to the desktop UI, and Microsoft seem to be focussing on Search and the Web.

Try it out for yourselves! I think it’s awesome.
