Where do people draw the line between a PKM (which is yours) and team documentation (which belongs, presumably to your team to which you have a transient relationship with)?
personal notes become cryptic team notes when you leave. If something ought to be team knowledge before that, it needs to get translated into a form that more people can easily read.
Product focused (plans, documentation, snippets) notes for team, people focused (1-on-1, performance review, birthday) notes for personal.
