Happy Birthday Dart

Dart was (officially) released to the world on October 10th 2011 at the GOTO conference in Arhaus.
Here's Gilad Bracha, talking about Dart last year:

Happy birthday Dart! A lot has been achieved by a lot of people - svn is currently on revision 13458, which is a lot of commits for any project.

Dartwatch was also started on the same day :), so happy birthday Dartwatch, too.
