I’m not sure about the name or whether it will be a Google killjoy, but yesterday Vivísimo open to the public their consumer search service called Clusty, which utilizes results from Yahoo’s Overture engine.

At the forefront of Clusty is Vivísimo’s topic clustering of search results (hence the name). Searches can be preformed across web, news, images, shopping, encyclopedic and something called ‘gossip’.

Hidden behind the ‘Customize’ tab in Clusty are options to span your searches across eBay, Slashdot and Blogs! (although I’m not sure why they separate Slashdot and Blogs)

Still, Clusty is impressive and worth a look.

Oh and soon to come is the obligatory browser toolbar. I wouldn’t be surprised if you see a desktop personal search offering as well, but that’s pure speculation on my part.
