Earlier quoted context omitted.
While I think the app and service has gotten much worse in several ways post-Elon, I do see way less crypto spam than before FWIW. The "For You" tab now actually sometimes even surfaces tweets I'm interested in too now. Performance and general stability has absolutely fallen for me though, and the launch of the DeSantis campaign on Twitter was a technical embarrassment/disaster as far as I could tell.
For me, the Twitter Blue boost has really led to a general drop in quality. I find that Blue subscribers typically don't say valuable things and are some of the most uninteresting people on the app, and yet they get boosted right to the top.
It's remarkable, and sad.
