Competition is good. Not that Google has anything to worry about, certainly not by Wolfram|Alpha, the new computational knowledge engine. But somebody at Google probably noticed the advantages of Alpha and tried to figure out a way to simulate at least some part of Alpha's capability using Google's existing search technology. Google Squared is another one of those Beta features that oozed out of Google labs. Google Squared returns results for information in a tabular form.
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.
