Well, I've been doing it for over 22... 23? years. I still get regular emails from readers every other week, and I just share the RSS feed (full text, by the way) and have a bot on Mastodon (previously on Twitter) that posts new links or major edits (controlled via post metadata).

I keep writing (https://taoofmac.com) because:

a) my wiki (looks like a blog, but it is a wiki, roughly 9500 pages of it these days - https://taoofmac.com/static/graph) is a public notepad of sorts, and I often do stuff that is either unique enough to not be documented anywhere or of interest to some technical fields (so many people found me because Google search used to work).

b) I refer to my notes frequently and share them, and it helps if they can be made public, especially when dealing with customers.

c) writing is sort of what I do. I like it, and it greatly benefits my ability to recall things. Every engineer on the planet should know how to write and communicate effectively, simply because explaining things always improves your ability to reason about problems.

That said, it's kind of weird to search for something I need to fix and come across my old self from 5-10 years ago.
