New Kid on the block

There is new clustering based search engine online (kosmix)more the merrier! especially now, when google is getting ineffective for some search queries- There are already few well known clustering engines like clusty. But they lack the reach of Google in terms of popularity and the depth of search result, hopefully Kosmix will be able to change that.Only time will tell how well does Kosmix fair against the old boys. Kosmix is running Health search as a demo and it looks really promising. Healthline is another healthcare targeted search engine. Clustering based search engines are good tools for Market/Competitve Intelligence folks, so pray that they will add your business domain to their clusters-
