The original Google Real Time was a fantastic search tool combining the comprehensiveness of Google search with the immediacy and coolness factor of Twitter. Google cancelled its deal with Twitter after only a little while probably because it was too much of a good deal for Twitter and users alike.
I really missed Google Real Time having lost a great tool in which to stay ahead and on top of things in a way I was unable to otherwise. I was thrilled to have discovered the Firefox Google Real Time search add-on and highly recommend it to everyone interested in getting a leg up on the competition. Fantastic tool.
