I've been a long-time Twitter user. I don't hate Elon, so when he bought it I was cautiously optimistic. I deactivated last week. The platform is bad and getting worse. It's scammy and spammy. Everything is designed around garbage engagement, so that the X team can brag about how good the product is doing.
What is garbage engagement? I think its entirely reasonable that an algorithm shows you things that you engaged with. It would be weird if it didn't promoted stuff I didn't engage w/.
A parallel term is "hate click", where there's a headline that's so stupid or off that you click it just to see what the hell they were talking about.
An example of this vile genre was someone tweeting about how:
"Teachers make plenty of money, and I think they should provide school supplies to their students out of their own pocket instead of making hard-working parents pay for them."
It was a message _designed_ to get people to yell at them, and for all of that, it wasn't any of the really hot-button stuff around politics, race, or any of the other divisive things that drive antagonistic engagement.
Twitter could have (and previously did) reward all sorts of other types of engagement, but the shift to rewarding divisiveness was just at another level.
