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