I am amazed and perplexed by Twitter all at once. I am amazed how it has become so popular so fast. Twitter was able to track 'tweets' (Twitter messages) that related to the Superbowl during the game. Not only does it show you the world-wide interest in the Superbowl, which we know, but it also shows you how fast Twitter has spread around the world since it started in 2006 right here in SF.
Other interesting facts: seems like more people were interested in Europe than Canada. South Dakota doesn't even show up on the Twitter radar but Laos and Cambodia does.
