My site is now an HTML & CSS website, just like the old days. I've had a blast rebuilding it in this way. The approachability of making updates to the site is off the charts, and the speed that it is served by GitHub Pages makes me smile. For some reason it's just more fun to make this sort of site in HTML & CSS.
At the moment it is pretty simple to make updates, but there is sort of a checklist of things to remember. I'll use this post as an example of how I go about adding a new post to the site:
Is it annoying to have to manually update things like the blog index and the RSS feed? Typo-wise, yes, it is easy to make a mistake. Time-wise, I haven't found it to be a bother as of yet.
While it is a little more time consuming working in code this way, it's at least consistent. When I'm working in a software like Micro.blog, I'm usually writing in Markdown, but sometimes I need to bring in HTML code anyway, and it gets confusing. Then if I'm making tweaks to the design, I have to go do that in a different webform while also maintaining a change history in a separate file in git. When I change CSS in blog software it might take effect instantly, or it might not. The particular CSS I'm changing might work just fine, or it might need an !important tacked on to it to work.
