I recently heard about Google Squared on Twitter and followed the link to find a fantastic search engine. I might call it a knowledge engine actually. If you click on the title of this post you will go to Google Squared. Type a topic in the space...I used roller coasters...and click square it. Wait a second or so and you will be amazed at what you see. Squared is part of Google Labs. This means it is in beta...or the development stage. I love anything Google especially since everything is free, free, free!
