It took me a few tries (divided attention #FTW), but I realized that after messing with blogs for over 10 years, I’ve seen all the things! Way back in the beginning was Movable Type (which I didn’t realize was still a thing), followed by PHP-based CMS like Textpattern and Nucleus CMS, and then a brief flirtation with Blogger (someone made me do it). I have somehow avoided ever having to maintain templates for WordPress (?!). These systems all come back to some pretty basic concepts around templating.
The one snag was loathing having to do anything with ruby. I have never had anything but grief and pain installing ruby anywhere. But hey! We have docker now! Put it in a container and forget about it. WOOT!
