I'm surprised no one mentioned the reason Nintendo disabled Swapnote. It was that the feature was used by child predators to produce child pornography. Nintendo of course is going to be cautious to allow online communication in a nonmoderated format. Until they grasp a way to circumvent that, Nintendo isn't going to provide such communication easily.
