I've been doing this too, but as a Python expert who always meant to learn Ruby but never really got around to it, I hate having to wrap my head around the suite of Ruby development tools (Bundler and the Gem system etc.) to do local builds, and it's currently taking up a seemingly absurd amount of disk space when this is the only reason I have any of it installed. Considering switching over to Nikola soon so that I can just use Python in the ways I'm familiar with.
