This lets anyone on Twitter send you a private message, regardless of whether or not they’re following you. Previously, direct messaging has only been possible between users who follow each other.
The current implementation doesn’t pose a major threat to established messaging services due to an account limit of 1,000 DMs sent per day. Once you hit this limit, you won’t be able to send any more DMs for the day. The update is currently rolling out to App Stores around the world so check back in a few hours if it’s not live yet.
Should you select to receive direct messages from anyone, keep in mind that any Twitter user will be able to send you direct messages — again, regardless of whether or not they’re following you back.
Once enabled, a new Direct Message option will become available on your contact page in Twitter for iPhone and iPad. The company argues in a blog post the feature opens up “a powerful and engaging messaging experience†for users, even “beyond the confines of their contacts.â€
As a result of this change, non-US account information is now handled by Twitter International in Dublin, Ireland and subject to Irish privacy and data protection law, which is based on the European Union’s Data Protection Directive.
The new update is available for free at App Store..
