the problem with obsidian is it can be anything.
some people people take a more Getting Things Done (GTD) approach, or zettelkansen approach, but mine is just to have notes about things that I go back to and build upon, and any time some page gets too big I comb through it, separate things into their own pages, and then [[wiki link]] to them and build a surfable lazy-not-quite-wiki, with pages I update as I learn new things about them.
while I'm not as pretentious as to label this anything but 'going back to my notes', most resources on this style will be under the keyword evergreen notes if you want to learn more about other people doing it
But obsidian can twist itself to fit any given notetaking strategy, and moving yours to another type is easy enough, you just get new plugins and change some of your headers, in many cases.
so it's more about making obsidian fit what's best for you, and knowing where things can change if you want them to. Your goal is externalizing your memory to paper, so you can use the resources you would for active memorykeeping and recall for other things. Or as quick reference. But memory is fallable, computers are less so.
one of my favorite takes on this is: (warning: computer-toucher tier)
