Google has announced their new search service Google Squared last month. It has finally gone live for public usage.
This service would be useful for those web users who are amazed to see the capabilities of Wolfram|Alpha.
Google Squared is somewhat similar but in a very crude way.
You start off with keywords like Digital Cameras. The search engine would do the hard work of finding out relevant data and place it in a spreadsheet format.
Users get the option to add rows and columns with additional data which is then used by Google to add more information.
