Eurovision Song Contest 2011 – tweets visualized
Eurovision song contest is a great example of networks: people tend to vote their neighboring country. In twitter one could follow and comment the pan-European event using the hashtags #eurovision, #esc, #esc2011 and in Finland #euroviisut. To a network analyst the @-mentions are the most interesting: who mentions whom. A tweet using one of the #-tags and an @name means a connection between two tweeters.

The most active tweeter was @davis3xm. Overall 64187 tweeters used the hashtag during the 4,5 hour period and 6378 mentioned someone else.
