Meanwhile, in Obsidian:

Logseq is great. Native outlining, org-like tasks, the power of Datalog. But Obsidian has the Dataview plugin. What you feed it looks a lot like SQL.

TABLE
  length(rows) as "Notes"
from ""
where isa != null
GROUP BY isa
SORT isa ASC

I kinda know SQL already. Enough to know what to look up to make a table of note types.

Nope. Haven't settled on One True Note System and I likely never will. But at least I'm enjoying myself.
