Twitter is running a new test to show the quote tweet counts. One of it's objectives it to make conversations easier, and making the count more obvious it hopes this will advance towards the goal.
“A few months ago, we’ve made Retweets with Comments more visible when you tap to see Retweets on a Tweet,” a Twitter spokesperson wrote in an email to The Verge. “This is available to everyone. Now, we’re testing making Retweets with Comments accessible directly on the Tweet and new language (Quotes) to see if this makes them easier to access and more understandable.”
