My main two use cases so far have been services and command line tools where it's not worth taking the effort to manage memory. The former I would have previously written in Java or C# (yeah, tie me to the cross right now language hipsters, I don't care, I already said I'm a pragmatist), and the latter in Ruby or Python.

I actually enjoyed going from dynamic to static typing for command line tools, the compiler saves me a lot of time tracking down bone-headed errors, which are typos in variables 95% of the time.
