@seachanger from my perspective, it absolutely was not and once a tweet got Out There it would be the same replies over and over, maybe people replying to the top two bad replies and replying-all so there's now an argument in the mentions (arguably even more annoying). And then if it gets to big, it would be QT-ed, which led to even *more* of the same replies and same QT notifications.
The only actually good feature twitter had in curbing that was being able to switch off replies.
@seachanger that said, the QT feature was very cathartic from my end, meant I could pick a couple of bad replies at random and set my followers on them, but in my experience it was never, in any way, constructively helpful to stopping the reply thing because at the end of the day it's just jerks being jerks
