No argument here, that’s a fair and thoughtful response, and you’re not wrong regarding the prejudice against self-hosting (and for what it’s worth I absolutely come from the era where that was the default approach, have done it extensively, like it, and still do it/recommend it when it makes sense).

> The Geek Code, developed in 1993, is a series of letters and symbols used by self-described "geeks" to inform fellow geeks about their personality, appearance, interests, skills, and opinions. The idea is that everything that makes a geek individual can be encoded in a compact format which only other geeks can read. This is deemed to be efficient in some sufficiently geeky manner.
