I signed up for Threads at the weekend. Never really used Twitter - had an account years ago but it's since deactivated, and it's recently been changed so you need to sign up just to read tweets (lame) whereas before you didn't need to and anyone could just read them.
The signup process was fairly straightforward. Haven't used it too much but I'm amazed it's had so many signups in such a short time. I guess people must really, really not like Elon and/or what he's done to Twitter.
