I have had the exact opposite experience. Do you remember how used to take a second for replies to load under a tweet? Now it’s instantaneous. My suggested feed is a lot better too.
To add another data point from someone who used to use the site regularly but still occasionally checks in once and a while, I have noticed a significant degradation in quality for the main feed and random outages/errors seem to crop up a lot more frequently. But aside from our respective pieces of anecdotal evidence, we’ve seen how pathetically they’ve been recently handling scaling and technical issues with high traffic events like the Desantis campaign announcement.
My suggested feed is absolutely useless, I'm not interested in what Musk has to say and I'm especially not interested in the unfiltered mouth diarrhea from MAGA morons like MTG. I don't even live in the US, why would I be interested in seeing it?
It's working perfectly afaict. "What is a woman?" for example was streamed a gajillion times just fine. The 700k stream of DeSantis or whatever took twitter down though, I doubt it will next time..
Honestly, no, I don’t remember, but my mental model of replying/threading on that site has been broken for a very long time. I’ve never been very sure how it works, or if it’s working properly, so I’m probably not the right person to ask about that aspect!
