Twitter changing replies so usernames no longer hit 140 character limit
Twitter shared today that it has finally flipped the switch on no longer counting usernames against character limits on tweets. Since tweets are limited to 140 characters, usernames for mentions and replies shortened the amount of characters you could include in a message.
This change was first detailed last fall when Twitter stopped counting media like images and links against the character limit, although the username rule has taken a bit longer to implement.
