Twitter Inc. may be preparing to raise its character limit for tweets to the thousands from the current 140, a person with knowledge of the matter said.
The maximum number of characters in a post could be raised to as much as 10,000, said the person, who asked not be identified as the changes haven’t been decided. A tweet that long would be roughly equal to a 20-minute speech. The number could be half that, depending on how users respond to trials, the person said.
