Direct Message can now be sent to you by anybody, regardless if they are following you or not. Twitter has announced that:"Twitter is rolling out an option to ease the use of direct messages. Traditionally, Twitter has allowed users who follow each other to send direct messages back and forth, or for users to send direct messages to accounts that follow them. A new setting, that appears to have been rolling out over the past week, allows Twitter users to receive direct messages from any follower. "If you check this option, any Twitter user that follows you will be able to send you a DM, regardless of whether you decide to follow them back," says a note before the option is turned on.
