Celebrities react to Twitter doubling its character limit from 140 to 280

- Why? Twitter's own research shows found the current 140-character limit is "a major cause of frustration" for users who tweet in English, but not in other languages such as Japanese/Korean/Chinese.

- The longer 280-character limit is only available to a select group of users for now.
