I mean if I'm learning something new, let's say type embedding in Go, and I need to refer to it later, 1 - in most cases accessing it via a Google search is much faster than referring to my notes, 2- in 6 months, probably someone has written a better explanation for it, which probably will rank higher in Google results, and 3- in 5 years, it probably is obsolete anyway.
More fundamental types of knowledge are not going to expire, but the first two reasons are still there.
I see the need for a more temporary note-taking, say what actions the team is going to take after this meeting, but I think that is not what most people on HN mean when they talk about keeping notes.
So my question is: what are the topics for your notes, especially in the context of retaining knowledge for the long term?
Much appreciated!
