"what you do with your notes after what you’ve shown here?"
I click them and start writing and (as Stephen says below "this my brain does, not my software.") Still I would say that for me, tech stops a bit later (techno-optimism :-).

"how do you actively revisit and reuse them?" I revisit (click) them as often as I need to come up with a sentence. Think of it like turning cards face up in the game of Pairs (aka Memory or Concentration) -- just that it won't cost me scores. And it's more effortless (no popup or page turning).

As for "reuse" (after writing), this applies more to the other sort of notes I mentioned (leading to my embarrassing 127.0.0.1 wordpress pages) where I would say, with Stephen again, "the magic happens in the creation, not in the subsequent use".

"Do you actively use them to write papers, articles, blogposts, other?" Yes, mainly blogposts. Fortunately I don't have to do any more academic grind work with boring references or similar formal work. This may have shaped my practice. My messy map suffices as my outline.
