That thread was super cool. Is there a subreddit for "how they work" kinds of things like this? I mean obviously this person does stuff like that on Twitter, but I have always hated Twitter's format and never know how to navigate things properly. (Plus now it's a total shitshow with the recent corporate drama.)
