Added some of my old posts from the old blog and realized that the time on those is all around midnight. I use the schedule post option in MB, and while I scheduled a day for the past, I didn’t schedule a time.
Another thing I learned: footnotes, which I used to use on my old blog, still work here in MB. Emacs converts those to lines of HTML when I export to markdown and it works fine. I need to adjust the CSS around those a bit, but otherwise it works fine.
