Twitter has removed the 140-character limit from Direct Messages (DM). This allows people to use Twitter’s Direct Messages feature to chat with their friends without having to curtail their thoughts to fit within the 140 character limit. This change does not affect publicly posted Tweets, which must still be 140 characters or less.
The removal of the character limit for Direct Messages started being rolled out on August 12, 2015, on Android and iOS apps, and on Twitter.com, TweetDeck and Twitter for Mac. Those of you who cannot wait to try the new, longer, Direct Messages should make sure your using the latest version of their apps. Twitter’s blog also notes that sending and receiving Direct Messages via SMS will still be limited to 140 characters.
Those of you with a lot of verbose and loquacious Twitter friends may be fearful of the length of the messages they might send you. Or, maybe you are looking forward to sending exceptionally long Direct Messages to some of the people you follow.
Personally, I suspect that it is only a matter of time before spam accounts and brand accounts take advantage of the longer Direct Messages. Now might be a good time to go into your Twitter settings and uncheck the box next to “Receive Direct Messages from anyone”.
