Twitter has a great feature of showing you the @reply messages by the people you follow, only if you follow that same person as well.

For example, if you sent me an @reply message to me ( @djloche ) that message would only show up in the feeds of your followers IF they followed me as well. This means you can have a conversation about the latest film with me, the party last night with your co-workers, and a pancake recipe with a friend that really loves pancakes - and there won't be any cross conversation unless there is a natural crossover in the social groups.

I guess that helps quite a lot in preventing group conflicts from getting out of hand accidentally. It seems like a weaker control if someone is deliberately trying to get involved in a conversation where other people would see them as unwelcome.

They can all choose to block him, though. And they don't need to include him in their replies.
