At work, I keep my notes in text files or in a physical notebook. A new text file every day, named by date. (At home, I use a wiki)

I've yet to find a system that works better than that for me (obviously, I suppose, or I'd be using it). Finding stuff in the notes is just a grep away.

not anymore, converted over to logseq a while back and once i got used to the tagging its just quicker.

nice daily journal too. We use onenote for work stuff - shared stuff anyway
