No one probably knows.
This doesnt look like a thought-out rebranding but a spontaneous decision.
And thats exactly what it is.
But the problem isnt even so much that Twitter is a mess.
Its certainly not cool, but on the whole, its not terrible.
Even the logo was changed several times in a row, slightly changing its drawing.
But thats not the main thing; the problem is that the name X is really bad.
Why is it bad?
Oh, come on.
For starters, its IMPOSSIBLE TO PRONOUNCE.
What do I call a social connection?
Hey, did you check out X today?
Its such an interesting thread there; people have left so many Xs!
Its absolutely not a brand because its just a letter.
Its hard to brand a letter, especially if its one of the most used letters in the world.
Everyone likes X; everyone uses it.
Its used in the names of smartphones, cars, shampoo, hotel rooms, and so on.
This letter is really cool as part of a product name.
But not as a brand in itself.
Thats the details; that was Musks decision, and we accept it.
