I am one of the worst posters here, I think.

Not that I'm bad at Posting -- just, I have no intuition or proprioception about Posting HERE, in this space, under this landscape/architecture/rules.

I think the person who is best at posting-here -- that is, not "who has the best posts" but who uses the medium and affordances to the maximum possible intent and impact, and fluency, as far as I can tell, to the limits of my own social/platform literacy,
is @futurebird

(If you just say "well, that's just your posting style -- it's off-meta and not the natural style of the platform" then fine okay, but @gdkar still did it first and better than me.)

@gaditb I just don't know that there's a standard "natural style of the platform", I think you're doing fine. (And I think your posting style and @gdkar 's are different, though I like both.)
