That site I mentioned earlier today, nitter.net, that seemed to be mirroring Twitter posts and thus made it possible for me to again read that content without having a Twitter account -- which became impossible on Twitter as of June 30th -- now shows no recent posts by the people I generally read, like Marcy Wheeler, and the posts it does show are in no clear order with huge gaps. For instance, turning to Wheeler, nitter.net/emptywheel now has these as the ten most recent posts, in this order from top to bottom: 14 May 2022, 29 Jun 2022, 24 Jan 2021, 13 Sep 2017, 23 Mar 2020, 23 Mar 2022, 15 Nov 2020, 11 Oct 2020, 18 Apr 2019, 27 Jul 2020.
So my best guess was something changed at Twitter to undermine nitter's ability to show recent content there. Ah well.
But then I tried looking at twitter.com/emptywheel. I can't get there directly: Twitter still takes me to a generic home page, as has happened for the past three weeks. (And that home page now isn't even functional.) But if I find a specific emptywheel Twitter post via a search engine, I can click on that, and I can go from there to Wheeler's timeline on Twitter.
And there I find that nitter is in fact mirroring what is currently on Wheeler's timeline: the same posts in the same order. So actually the content on Twitter is suddenly random and full of gaps? It's not just emptywheel; I tried five other journalists whose work I've read in the past:

https://twitter.com/joshtpm
https://twitter.com/MuellerSheWrote
https://twitter.com/mattyglesias
https://twitter.com/darth
All of those now show a random selection of old posts. And some other accounts I've frequently read in the past now show as "haven't tweeted," i.e., ever, including David Frum, Tom Nichols, and Anna Bower -- even though Bower's tweets have been quoted here just in the past couple days.
