I might have missed a few names, but I'd like to contribute a list of folks and sites from the old Flash community who seemed like rock stars (in order of how much I idolized them).
Once I typed it up, I realized it was all dudes, so let me first link to https://flashgoddess.com/spotlight/ , who shone a spotlight on the women who worked in the same space. (Shoutout to Lisa Larson-Kelley, fellow alumnus of FlashCodersNY, and Stacey Mulcahy, whose hilarious AS2-to-AS3 migration talk was fucking awesome!)
If you wish to view any of these links, I recommend pasting them into web.archive.org and setting the Wayback to the mid-to-late 2000's.
mrdoob.com (Mr. doob, later created three.js)
audiotool.com, lab.andre-michelle.com (Andre Michelle)
wefail.com (Jordan Stone, Martin Hughes)
gskinner.com (Grant Skinner, later created EaselJS, etc)
quasimondo.com (Mario Klingemann)
bytearray.org (Thibault Imbert)
bit-101.com (Keith Peters)
vectorpark.com (Patrick Smith)
hoogerbrugge.com (Han Hoogerbrugge)
levitated.net (Jared Tarbell)
blog.joa-ebert.com (Joa Ebert (also audiotool))

hospital.apoka.com (Edouard Artus)
kirupa.com (Kirupa Chinnathambi)
mosessupposes.com (Moses Gunesch)
gotoandlearn.com, theflashblog.com (Lee Brimelow)
Most of these folks also spoke at tech events, sharing techniques and hard-learned lessons. Like that time when Wefail gave a talk that took a memorably heavy shit on Jakob Nielsen. Hell yes.
Also worth noting the HBO Voyeur promotional site made by Big Spaceship: archive.bigspaceship.com/hbovoyeur
The Flash community was creative and groundbreaking as hell. Most of the folks who criticized it for being proprietary and insecure are lifelong users of proprietary, insecure platforms; the worst aspects of the Flash-equipped web linger still, namely ads, inaccessibility and site bloat; and let's face it, as capable as the modern web client stack is, it's lost so much ground to the walled garden platforms, that Steve Jobs's 2010 agenda can no longer be seen as anything but duplicitous.
Godspeed, FutureSplash! You were to good for this web.
