#RegEx is hell.
Took me a good while, missing around at regex101, before I figured out the expression I needed to handle cutoff points for my website's blog posts.
Then, oops, it turns out that #PostgreSQL uses a different form of regex that my expression didn't work with.
So I spent another half-eternity figuring out *why* it didn't work and then coming up with a different way to do it. Ended up going "oh, the second branch just needs to DO THIS" and then suddenly it worked.
On a brighter note, I just implemented Mastodon comments on my #blog test page, thanks to @dpecos's excellent repo:

Maybe someday I'll seriously try to make it so I can update my "finished/played games" thread through my blog, but for the time being I'll be happy to just adapt the #CSS to my site and see how streamlined I can make the process of posting/tooting and then tying the blog post and the toot together without extra, manual steps.
