I finally rewrote the blog engine behind this blog in a more modern PHP.
Ghost turned out to be more work than I thought to build a template with the features I wanted. It was easier to just rebuild it in PHP.
This design is mobile friendly. Please let me know if you see or experience any strange behaviors on either desktop or mobile.
I intend to make more changes over time. Currently I am trying to figure out how to build a better set of tags to make it easier to find similar articles (though most people seem to just read what's on the right/bottom navigation). The biggest change is the editor which of course only I use; it supports a better quality of text than the old one did—even real em dashes!
