Q: Who?
A: Twitter.
As a Social Media Manager I spend most of my day on Twitter, so I have noticed the recent updates Twitter has made. For instance, quoting a tweet had been such a pain in the past (see what I did there?), not enough characters, weird short links, basically a poor feature with good intentions.
The new format is fantastic. A quoted retweet is essentially posted as an interactive image, using significantly fewer characters while allowing one to easily access the original tweet.
