Effectively this means the choice for users are going to be to either sign up for free on centralized twitter and never pay a dime for any tweet they send or have to buy a very volatile shitcoin so that they can pay a lot of fee (up to $60) to send a single tweet! Not to mention that in order to view the tweets of other people they would have to download the entire ethereum blockchain and most importantly index it which would take up a lot more space then search for the tweets they want to see.
Nobody is going to chose the alternative!
You are correct that Ethereum in its current state would not be a good choice, but maybe the first iteration could be using DOGE transactions?
(HEY ELON!!!)That would introduce centralization.
Yes but there will be hundreds of websites serving the same purpose that twitter does now. Most users will use a centralized page that they like. If the page starts putting up too many ads or god forbid censors someone they don't like, the user is free to host their own site or use someone else's.
