Ask HN: Do other people keep developer diaries?

For a long time, I didn't have a cohesive way of keeping track of thoughts, ideas, TODOs, design process, etc. I had source code TODO comments, random screenshots of things I found online, and so on, littered throughout my code base and a "working" folder. Eventually I started keeping everything chronologically in a single Word document.

I think the closest I've seen others do is blogging the development process, but that's usually a bit more polished and focused on the end result of the thought process on each decision, rather than - for lack of a better term - going on a journey with the author.

Does anyone else do this, in raw, unpolished form? If so, how do you store that (notes app, document, blog draft posts, etc.)?
