The reason why Go is successful is because it's a very, very opinionated language, and for the most part its users agree with those opinions. And the opinions that they don't agree with don't detract as much as the opinions that they like. By being highly opinionated and predictable, it makes it easier to digest. I especially like the reformatting capabilities so everyone's code looks the same. The more people program the same, the more predictably the code behaves and the less overall problems.
