Forget the edit button, Twitter should have a "stop spread" option on tweets.
It's perfect for when that half-baked tweet you sent after a few glasses of wine is getting way more reach than you expected and you want it to stop, but you don't want to delete it.
I've noticed that most tweets that do well go through a sort of cycle:
1. People who follow you and "get you" like and respond 2. People who they reach respond and engage 3. It keeps spreading to people who have no idea who you are and just want to dunk on randos
Something spreading can feel fun in the beginning then quickly become very unfun.
Especially since negative sentiment seems to spread faster than positive sentiment.
