Twitter could raise character limit on tweets to 10,000 from current 140
Twitter has evolved from a messaging app used to send brief messages among friends, to a major communications tool used to disseminate news. During some recent "active shooter" situations, those pinned down in one location have used it to alert the public and the police to what is going on. On a day-to-day basis, Twitter has also become a way for the average citizen to communicate with people that they normally would never be able to talk to, such as celebrities, government officials and high-ranking corporate executives.
Twitter has already increased the character limit on Direct Messages, which are private tweets between users, to 10,000 from 140. The company hopes to have the new character limit in place for regular tweets by the end of the current quarter. In an effort to keep tweets looking the same as they do now, Twitter is reportedly testing a method that would keep the number of characters displayed at one time to 140. An icon would appear on the screen to inform the recipient of a long tweet that there is more to the message.
