Caution.  Twittervision (No longer available!) might make you dizzy.  Maybe it is also a cure for loneliness, if you can bear it.  It is certainly makes one ponder the meaning of it all.  These effervescent messages from real people around the globe, vanish as quickly as they appear, an alarming demonstration of time and space convergence.  Where are we headed? (Jan 8, 2011… this was fun but now seems broken).

Update 30/6/2018: New and awesome tweet map!!   Made by MapD.  Lets see how long this one lasts.
