Your friends on Substack are not okay
Life
By bolting on an algorithmic feed, Substack is trying to make a vertical. There was a brief window where the Notes feed felt sort of like if Mastodon might if your instance was taken over by people with a weird kink for FRED graphs and lefties who are too retiring to go Full Piker, but those kinds of temperaments aren't going to be heard in an environment with algorithmically driven incentives.
Anyhow, one less thing to not graze in the mornings.
