Twitter takes on messaging apps by removing 140 character limit from Direct Messages
Twitter is getting serious about messaging today. The social network has begun rolling out updates to its iOS, Mac, and Android apps, in addition to TweetDeck and its website, that remove the long-existing 140 character limit from individual direct messages. This change will roll out over the course of the next few weeks, so all users may not see the change immediately. The old 140 character limit for messages will remain for Tweets sent publicly and direct messages sent via SMS.
