The renaming of Twitter to X does not necessarily require the tweets to be renamed as well. Tweets have become so ingrained in social media culture that they might maintain their name, much like posts on Facebook are still called "posts"
Based on Elon's personality, I think it should be something goofy, or something that when you say it sounds rediculous
For example: Xo's
I just liked your xo
president just xoed about the incident
X's does not roll of the tongue very easily. Like tweet does. I think xip (pronounced zip) sound great. What do you think tweets should be called? @abbas143official
