Bluesky is a microblogging platform with some similarities to Twitter, but with several important technical and philosophical differences. I recommend checking it out.
Public profiles can be viewed without a login (here's mine), but if you want to create your own profile and write posts and replies, you'll need an invite. There's a waiting list. You can also let me know if you're interested - if I get any invite codes to share, I will.
Looking forward to seeing how this develops.
