There is an excellent podcast with Gilad Bracha on Newspeak at se-radio:

It was one of the most memorable and interesting podcasts that I have ever heard. Newspeak will likely remain one of those languages that I really want to learn, but won't find the time for.
Considering the speakers, I'm actually very interested in what Dart is like.
