Twitter is Removing the 140-character limit from Direct Messages
 

If you’ve checked your Direct Messages today, you may have noticed that something’s missing: the limitation of 140 characters. You can now chat on (and on) in a single Direct Message, and likely still have some characters left over.
You may be wondering what this means for the public side of Twitter. In a word, nothing. Tweets will continue to be the 140 characters they are today, rich with commentary as well as photos, videos, links, Vines, gifs, and emoji. So, start working on those sonnets.
