Yeah, fully agreed on that. Go just doesn't have as productive a framework like Rails. That's why I only use it for very small websites or even smaller API gateways. Or CLIs. Or network daemons.
I am not disputing your choices. Just wanted to give you the quick and intuitive (and likely misinformed) immediate reaction that I had from the article.
Keep making GitLab awesome. <3
Another thing is that there isn't a web framework like Rails in Go. Although I'm keeping an eye on go-micro and we plan to add that as a template soon.
