I've given up on using Hugo for this site & finally moved back to Perch. The awkwardness of updating a static site just got to be too much, so I stopped posting. Now I can post quickly if I need to, and even update via mobile if I want to.
I'm using Perch Runway now instead of plain Perch. Runway's "collections" map perfectly to how I want to organize my content, and their developer pricing for a non-commercial site means there isn't a price penalty for using Runway. Thanks, Rachel & Drew!
The biggest downside I've found of using Hugo for this site is that it's awkward to create a new post. I have to be at my computer to create a new file (can't use mobile), and then I have to generate & upload to the server. The friction is minor, but it's still a small annoyance.
I'm considering using a headless CMS like strapi.io to remove this friction, but at the cost of more complexity. Mulling it over....
Trying out the Hugo static site generator. So far I'm loving it. Wicked fast, easier to work with than everything else I've used.
