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. While the new option is fairly minor, it’s likely designed to allow brands and businesses to receive private messages from their followers. Twitter has partnered with a number of TV networks this year in an attempt to promote its social networking service.
