Though they did a limited roll out in September, today Twitter has announced that they are making the ability to tweet with 280 characters available to all. Well, all except those tweeting in Japanese, Korean or Chinese languages.
According to Twitter's original statement about the change (which as many Twitter changes, came with pushback from users) the exclusion of those languages is because each character can communicate much more. The new change gives users space to now tell more compete thoughts and according to Twitter, if the behavior is constant with what they saw in the test group, will be used sparingly after the novelty wears off.
Understandably, Users had some thoughts and special tweets for the announcement.
