Immutability makes social media worse. Immutability may make me consider my words before I write them, but it also prevents me from saying things I’m not sure about, from learning as I go, and from experimentation.

Perhaps more importantly, it holds my opinions hostage to time and to the progress of society.

Society would do well to be rid of social media.

twetch solves this by encrypting each post on the blockchain and allowing users to revoke access (functionally deleting the post for all users) https://twet.ch/inv/ratel

This is definitely a little bit of a different medium to twitter and likely the '1 post per block' limitation is great in this case. Think before you Zooko, as it's permanent and forever.
