In case anybody sees this comment: I am having a bad brain day today. I clicked OP's link a few days ago, saw a wall of text in a font that's really big on my 1024x768 screen, and never saw the discord link buried near the bottom of the wall of text.
Since nobody copied the discord link to this thread I never realized it existed, so I created a discord server of my own and then spammed the thread with replies pointing to it. I have now deleted all 20 of them.
I've decided /not/ to delete the discord server I made though, because now I realize the "official" discord that was created has over 500 people in it I am most definitely not touching that. That's an overload I know my brain won't deal well with - my upper limit for realtime chat is around 20 or so new chat messages per day.
So here's the invite code to my low-traffic server: https://discord.gg/ffDd8uW
And the moral of this story is, I guess, good web design that works for everyone. Medium is great on new computers... old ones, not so much.
