I remember when twitter first came out and people were talking about "tweets" and it sounded just as stupid as xing sounds today. But the word has made it into mainstream lexicon and been normalized. Just like "googling" something just means to search. Tweet will mean to message something. I think part of the reason he is abandoning twitter is because it is becoming increasingly hard to legally fight other people using the terms for his platform for other platforms. For instance Mastadon is using "toot" which started from "twoot" which started from tweet.

I also still think he is an idiot for abandoning a brand name that is literally in every house and on every storefront. Even if they cant defend the vocabulary to abandon it all is the dumbest business decision I've ever heard of.

p.s. for xing I like "kissing" since XOXO is hugs and kisses with the X being the kiss. Considering how homophobic Elon is having his platform being a bunch of people kissing would just be to perfect!
