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.
While Twitter is largely a public experience, Direct Messages let you have private conversations about the memes, news, movements, and events that unfold on Twitter. Each of the hundreds of millions of Tweets sent across Twitter every day is an opportunity for you to spark a conversation about what's happening in your world. That's why we've made a number of changes to Direct Messages over the last few months. Today's change is another big step towards making the private side of Twitter even more powerful and fun.
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.
