The author’s critique of the thesis that PKM tools lack evidence of impact in global knowledge is certainly interesting. But there is a fundamental problem that I state plainly as: what responsibility do I or any user have to this nebulous corpus of total circulating knowledge, anyway? I use Obsidian to organize knowledge around things that are personally interesting to me. That’s the “personal” part of PKM. I feel zero obligation to contribute that to some larger public corpus. I may do so at my discretion, of course. But holding PKM systems to such a high (and impossible to assess) standard is a mistake. I routinely play with my dogs; but what evidence is there that it makes the world a better place by some objective measure?
