Would love to see twitter become an API-first backend where you could chose different clients with different feed and recommendation algos. Not just basic info and tweets, but a full view of platform interactions will be query-able by 3rd party devs writing the clients.

Add on Lightning micro payments api to rate limit bots/spam, and also use LN for monetization to content creators.

They should also enable and cooperate with 3rd parties looking to archive historical accounts.
