In my free time I develop a static site engine called Hugo which is hundreds of times faster than others written in python and ruby and is super easy to install as it is distributed as a single binary without any dependencies. You can learn more about it at http://hugo.spf13.com .
This makes deployment much simpler than Python, which leaves the user to find all dependencies, which isn't as always as straight forward as it seems.
Also, with go.rice I was able to embed my static resources (.html mainly) right into the binary, giving me a single file to deploy, much like a Java fatjar.
This was actually a port of a small Python project to get the feel for Go, and I'm really sold on the "scp" style of deployment (I can get that from Java to, but Go seems more approachable for smaller projects).
The back-end of is written in 100% GO. Asset pipeline tools are mainly go apps as well.

I chose go because it is significantly faster than python, compiled, has a decent selection of libraries, and because I really wanted to learn go.
