I used Hugo's native `.org` file support for a while. It was… fine. There are some serious issues (for me) that I had with it though. The most salient one is that it didn't convert straight quotes in the source ("") to proper curly-quotes. (“”) I don't remember what else but I'm sure there was more than just that. I've spent a lot of time on the typography of my site and I wanted everything to be as perfect as I could make it.
