Twitter finally flicks the switch on 10,000 character DMs

Feel free to bombard your friends with effectively unlimited direct messages now as the social network enables a longer unbroken service

Twitter users can now send direct messages (DM) of up to 10,000 characters, three months after the company announced the forthcoming change to users and developers on its development blog.

The new DMs, which are intended to be of effectively unlimited length for the typical user, are part of the company's long-running effort to upgrade its messaging service to make it a more competitive alternative to market leaders such as Facebook's WhatsApp and Messenger apps.
