Maybe! The people who are still left must really like Twitter. I think charging a token amount to limit who can post from a Sybil attack mitigation perspective might actually be reasonable, and it’s exciting that someone who doesn’t care if they lose is willing to perform the experiment.
If you’re not willing to pay at least a dollar to post, maybe your content doesn’t have any value to the audience or platform. I’d pay $1 to keep posting here (probably more! But don’t tell the YC folks).
