Right now if you use Twitter’s Direct Message (DM) system you’ll notice the message is limited to 140 characters. Starting in July, Twitter will remove the character limits when sending DM’s.
Instead of breaking thoughts into 140-character messages you’ll be able to send your thoughts in one DM. The standard Twitter system is still limited to 140 characters.
DMs have increasingly become more flexible, powerful, and more easily used between individuals. Twitter looks poised to make it into a full-fledged competitor for platforms like FB Messenger if it continues down this path.
