Twitter ends Direct Message character limit
There is a new limit in place, but it’s a far more generous 10,000 characters. This could indicate that Twitter is testing the waters for longer-form messages throughout its service. Or it could just be giving people more freedom in a bid to attract people away from Facebook Messenger and other messaging apps that let you write to your heart’s content.
From its perspective, Twitter says that it is removing the character limit to make Direct Messages “even more powerful and fun.”
