Twitter’s 140 character limit formula has worked well for them. It’s an integral part of the microblogging service so we don’t expect tweets to change much in the foreseeable future. However Twitter has changed the rules for direct messages or DMs. The company has announced that it has removed the 140 character limit from DMs.
It’s now possible to chat as long as you like in Direct Messages since they’re no longer limited to 140 characters. The tchange follows after Twitter allowed group DMs and allowed users to receive DMs from anyone even if they didn’t follow them.
Tweets are mostly meant for the public while Direct Messages are private between one or more recipients, so they’re more focused toward private conversations, so this makes a lot of sense. So Twitter is making private conversations on its microblogging network more powerful and fun by doing this. Again, this changes nothing for tweets, they’ll continue to be capped at 140 characters.
The company has already rolled out the change across its Android and iOS apps as well as on Twitter for Mac, TweetDeck and on twitter.com. It will roll out worldwide over the coming weeks. Sending and receiving DMs using SMS will still be limited to 140 characters though.
