Ruby has Matz, C# has Anders Hielsberg, and Erlang has Joe Armstrong, one of the creators of the language. He has a blog here. I’m glad to see that as the language really starts to take off, one of the creators is still in the industry and there to be a part of it. That sounds odd to say, but it took Ruby 11 years to really see a critical mass, brought on by Ruby on Rails. It took Erlang 21 years.
