In more simple words, to able to send and receive DMs (Direct Messages) on Twitter both interacting users must follow each other. This is not required anymore. Now you can receive Direct Messages from any Twitter follower irrespective of you following that user or not.

If more Twitter users activate this feature, it should become very useful for businesses on Twitter. They can send special coupons and deals information privately to users without having to follow each and every follower.
