I worked on a project with go, and initially i liked it. Because the new way of thinking, and the fast compiler. But both the error checking, missing of generics, and missing of real functional programming paradigmas, required me to write something very simple in a complex way.

I concluded that a simple webapp, is better written in python, and go was not the way togo for my project. In python you can quickly generate json from objects (yeah you can in go but only with ugly string comments). All in all, go has its place, but when you start a new startup, watch out with go initially.
