Essentially, before posting a tweet, users will be able to select one of three options: everyone (standard Twitter, and the default setting), only people you follow, or only people you mention – thereby controlling who can (or cannot) reply to a specific tweet.
This new setting is all a part of Twitter’s plan to give users more control over their conversations across the platform.
Here’s a quick look at exactly how the feature works:
Testing, testing…

If users select either the “only people you follow” or the “only people you mention” options then their tweet will be labelled and the reply icon will be greyed out so that it’s clear for people if they can’t reply. See image below:
People who can’t reply will still be able to view, Retweet, Retweet with Comment, and like these Tweets.
