Wow, what a weird rabbit-hole I just ended up down.
So, the “Spread Mastodon" page (tutorial?) recommends a cool-sounding browser extension as an alternative to all those constantly-dead 'fedifinder' / Twitter-person-looker-upper-tools: the ‘Whosum Social Assistant' browser extension.
Sounds cool! Sounds like the correct solution to this problem!
Every other year the sentiment towards The Simpsons swings from "I don't mind, they're having fun with what they have, the show is even getting a little introspective" to "They should've ended 20 years ago, which is coincidentally when I stopped watching TV in general" either relative indifference or wishing the medium of television didn't make it through the 00s.
