As mentioned in the first post, I'm using Denote to manage my blog.
One issue I identified with it was the potential instability of links to specific blog posts, since the file names can change automatically, due to, for instance, changes to the filetags.
I'm currently attempting to fix this using the denote: link format, which only uses the (stable) timestamp-based identifier to link to a given note.
This should work for links between Denote notes (or the whole system won't work), but it broke the first time I tried to link to a Denote file from outside the denote-directory.
It turned out this was just happening because I had set denote-directory incorrectly in my publishing script. This early problem highlights the potential issues that can arise from having a separate configuration for the blog, isolated from the rest of my Emacs environment, but I'd say it's still a net positive; for one thing, it should make building the site within a CI pipeline easier.
