I am thinking of documentation sites and blogs in the same categories, because I use them similarly. I create blog posts (documents), they have titles, categories, and they link to each other.

I'm being a bit dramatic, but it's to stop people from using SSG. I don't like working on said applications because adding every little feature is a pain and adds to the build time. Running a simple service and DB is easy - I've been doing it for a decade. I ran blogs and sites with databases when I was in HS - surely big companies can do it and put cloudflare in front of it.
