The Twitter rebrand began about a week ago. Elon Musk kicked off a rebrand to ‘X’. Twitter branding is gradually fading in all shapes and sizes. X has a new name for Tweets, in addition to a new logo, name, and handles. Tweets are now referred to as ‘posts,’ which makes sense. Please keep in mind that this change is not yet visible to everyone because it is still associated with a beta version of the app.
