I assume twitter blue offers other perks, that people might want without the shame of it being publicly known.
I heard of several people paying for blue to be able to edit tweets and such before Musk bought it.
I thought that making blue check marks purchasable was one of the first things Musk did at Twitter after firing everyone.
I don’t know what it was called, but the purchasable blue check marks thing built off of an already existing service. It might have had a different name, I don’t remember.
Paying for Twitter Blue wasn’t a thing until after Musk bought Twitter
Their posts get prioritized in the algorithm iirc
By a vast margin. Replies are apparently unusable as a thing for communication because if you have a checkmark the algorithm ignores any other consideration.
