SHORT POST ON LONG POSTS
Increasingly I think short _personal_ posts don't amount to much change or exploration between people... or short posts on other people's stuff also lacks a lot.
It works if there is already a level of understanding and progress made yes (including existing echo-chambers, computer-only stuff, people already awake or with similar conclusions).
But not enough edge there.
I'm not claiming long is best, just longer beats writing less or always short as it's much better towards improvement and change or many things.
