For many, wolfram alpha is the search application that can overthrone google. It does not give you a series of web sites where you can find the information that you are searching. Instead it tries to give you the exact information that you are searching.

If you insert a word like milk the search box will give you detailed information about milk
cool, isn’t it?
It’s very incomplete but it is certainly a very good concept. Maybe google will buy it and merge it with its search tool.
Is this thing gathering information from other sites and presenting it or does it only show it’s own content? If it gathers from other pages it would probably be a copyright intrusion, since it doesn’t site any sources or anything.
