Just read an article about the founders of Ruby on Rails. It pretty much touches on things that I've found to be true myself. Yes, they're good coders. Yes they're arrogant. No, they don't play well with others.
Simply put, their vision doesn't work for everyone. You're either in their cult or you're not. And they don't care which, because they're rich and happy enough doing their own thing. More power to them.
