I just read about former Google employee Anna Patterson's new search engine Cuil. Apparently, the name is pronounced "Cool". It automatically categorizes the results and claims to have the largest index of the internet of any search engine, including Google.
If you try it out on Alfresco, It organizes and summarizes the pages neatly, although I have no idea why Alfresco magazine in New Zealand shows up first. The categorization panel on the right is interesting, although not 100% relevant. And why does an OpenText image come up next to the Download Alfresco link? Must be a few bugs, but it all looks promising.
It would be nice to give Google a little bit of competition.
