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.
Just heard from Twitter that they are lifting the 140 characters limit in their direct messaging. I believe it's a big move for Twitter to make a come back to compete with Whatsapp, Facebook Messaging and Google Hangout. It's something that they should have done a long long time ago.
I am eager to try it on my own Android App and Twitter.com web account. Sadly the 140 characters limit is still there. I guess I have to wait a bit as they did mention that they are rolling it out in a few weeks time frame.
We’ll begin rolling out this change today across our Android and iOS apps, on twitter.com,TweetDeck, and Twitter for Mac. It will continue to roll out worldwide over the next few weeks. If you can’t wait to try out longer Direct Messages, be sure you’re using the latest versions of our apps so you get the update right away. Sending and receiving Direct Messages via SMS will still be limited.
