This is great for Go and I'm happy for them. I feel like in my career many people are extremely intimidated at the prospect of using Go for more than a pet project. The best answer I can manage to get to the question of "why?" is that it feels unfamiliar to them. I think this is an unfortunate hurdle.

Hopefully that is just how things are in my little bubble (as this survey would indicate). I think Go is really cool and I will continue to lobby to implement some mission-critical systems with it.
