Figured it might be a good discussion question. Crossposted to !pkms@lemmy.blahaj.zone.
Especially as someone who wants to help grow !journaling@sh.itjust.works, and to participate to help it grow, but in the end I come from !pkms@lemmy.blahaj.zone and I think of what I have far more as a Personal Knowledge Management System than a journal. I spend far less time on personal feelings and thoughts and “what did I do today?” and a lot more on making it a knowledge repository for Future Me. And if what I do is actually pretty separate from journaling it would be cool to know so I don’t invade threads I shouldn’t be talking in.
It’s as different as apples and oranges in my opinion.
However, journaling can be part of a PKMS, if you link it in a meaningful way.
There can also be different kinds of journaling as you mention. I write a personal journal (mostly everyday, going on two decades). However I also have a separate “domain knowledge” type journaling thats less feelings and such but discoveries and insights.
If you haven’t heard of the concept of Zettlekasten, I’d suggest looking into that. As a neurodivergent it was a breakthrough that matches how my mind works when it comes to curating a PKMS in a relational manner.
