I know many of you have been keeping tabs on Wolphram|Alpha, the "long-term project to make all systematic knowledge immediately computable by anyone." Well, looks like Google has responded with their own tool called Google Squared. You can read up on Google Squared on the official Google Blog, but here's the scoop:

Google Squared is an experimental search tool that collects facts from the web and presents them in an organized collection, similar to a spreadsheet. If you search for [roller coasters], Google Squared builds a square with rows for each of several specific roller coasters and columns for corresponding facts, such as image, height and maximum speed.

I don't know about you, but that sounds awfully familiar. However, they seem to work much differently--Google Squared doesn't seem as focused on comparisons as WA. Still, all this and Bing in recent weeks has me thinking a lot about search engines.
