Why would I use Go instead of Ruby/Python/nodeJS?
* I can use go fmt to format my code and it'll look nice. So many people use go fmt that most code bases are very easy to dive into. They all follow the standard!
* No magic! You write what you want and the whole formality of the thing forces you to write better code. May be a placebo effect, but I find myself writing less buggy code in Go.
* Compile to static binary you can just drop and run -anywhere-. No rvm gemsets, no rbenv, no bla bla bla - you want your code running, period.
You can have maintainable and unmaintainable codebases in any language.
