Yes, you’re probably right on all three points 🙂
I have Joplin installed since a while, but haven’t explored it much yet. Currently for ‘wiki’ style notes I use a local wordpress instance I already used for journaling. There I use pages for wiki (and webmention for two-way linking), and blogposts for journaling. I started keeping daily logs some weeks ago, and I noticed how it more easily spins off public blogposts and wikipages with info, snippets and pointers. Doing that made me realise that I need to look at my own motivations and needs more, before trying to tweak the toolset. It sort-of works as is, but what is it I am trying to accomplish in the first place?
