I agree Go produces great software. But for the same amount of functionality it tends to require more lines than ruby. I tend to favor the more expressive language http://www.paulgraham.com/avg.html
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.
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
In the end, it's your call of course. But line-count doesn't say anything about a project's complexity. Go is quite verbose but with rigorous CI, tests, code reviews and linters, teams produce pretty hardcore and good software in Go, regularly.
