People love doing things that feel like work, but aren’t. I’m terrified of picking up new systems like this without having a purpose. I could spend hours building out a graph, admiring all of MY knowledge, but not really have any intended use for it other than telling others about it and how I’m going to use it someday.
So while I'd like to retain my knowledge and research somewhere, at the same time I don't actually use it???
But some writing I've done that will be relevant in the next years is writing ADR's (Architecture Decision Records) in my application about technology and architecture choices I've made, so I can look them up later, use it to train new people, and have a basis to challenge a decision on as well. That's more practical for my personal situation.
But maybe one day I'll be doing something more academic and will need a way to collate research and the like.
