OTOH -- Twitter (on the blockchain) supporting only ~10 tweets per second is a blessing in disguise that would drastically help improve the user experience by imposing a high cost on junk :P

Imagine a platform where tweets were so expensive only the rich could speak!

~$0.001 USD is the current cost for gas on Polygon for a transaction. If people have to pay credits to tweet (even this little), I would expect the quality to increase.

How will being attached to something as valuable as speech change the value of that?

Or similarly a world where one pays to read tweets.

People would get into bidding wars for the next tweet

Twitter could be improved by requiring a proof of work effort before posting any tweets. The effort could be computational, or just proof of fact checking and basic proofreading would go a long way.

"Proof of thought"

A pretty short blockchain that would be.

Twitter + proof-of-thought would be awesome :-).

Twitter is already an awful user experience.
