> But I suspect what will happen is people will continue to call it Twitter and the X name will not stick.

Me too, the problem is that you cannot convert X to a verb. "They x'ed this and that" sounds much dumber than "They tweeted this and that".

After "Let that sink in", we have "I X'ed Twitter".

I think you're right, HN and news websites are the only places that Facebook is referenced as "Meta", and that's been the name for a couple of years now.

You mean "Facebook" as a company name, presumably? Isn't the social network still called "Facebook"?

"The company formerly know as Twitter".

How about "the app formerly known as Twitter", to make the acronym read nicely? I think I'm indeed going to start calling it TAFKAT. :)
