A new Twitter update now prompts users to quote the Tweet. That means when someone clicks to Retweet, they are brought to the Quote Tweet composer and encouraged to type their own thoughts. The goal with this update is to get more users to consider why they are amplifying a Tweet, and then add to that conversation.
