1. Bob quotes a tweet from Alice he thinks his followers will find enraging
2. Bob's followers reply to the tweet with predictable outrage and abuse
3. (present system) Twitter becomes unusable for Alice as she is flooded with mentions from all of the angry and abusive replies to Bob's quote
3. (proposed system) Alice is not shown any of the replies to Bob's tweet. Bob's followers scream into the void.
4. (proposed system, cont'd) Bob's most clever followers know replies will not be seen by Alice, so they @ her directly. However, Twitter is even more clever and has a super-advanced algorithm that goes "if you follow someone who quote-tweeted someone else in the past 48 hours, @-ing the quoted user will not show up in their mentions." New accounts (less than 48 hours old) are also unable to @ anyone at all.
There, I fixed Twitter. Jack, I'll even write out some Jira stories for a very reasonable fee.
