I wonder if this sort of thing belings to a certain kind of organisation, or type of career. I can certainly see the value of "we have all of <brilliant engineer's> technical notes going back 43 years!" but in my experience, it's rare to meet a "brilliant engineer" who'll stay in one position for even a decade.

Personally, I've been in many 2-15 year employments where I made copious notes - but I did so in whatever wiki my department was using. I've never had the opportinity (or, for that matter, much desire) to bring those notes with me to the next position, as they were (a) specific to that place or task, and (b) quite certainly proprietary (if far from high-value industrial secrets). Detailed notes on the inner workings of an in-house framework, or end-to-end credit card processing flow, just aren't that relevant when your next role is steward of a 25-year-old national tax reporting platform.

I've done a few blog posts, but haven't generally felt the need to share my brilliant thoughts with the greater world, those were just my personal musings (as is this piece right here).

Don't get me wrong, I'd love to _be_ in a position where such long-term usefulness was expected.
