All of a sudden, a Twitter drone doesn't seem like such a crazy idea. The social network applied for a patent earlier this year for a "Messaging-enabled unmanned aerial vehicle," which describes pretty much what you'd expect: A drone that can post media to a Twitter feed of its own. Beyond that, Twitter users would also be able to control certain elements of the drone with their own posts. That includes its subject, location, orientation and more. When asked for comment by CNBC, a Twitter rep simply said, "Two words: Drone selfies." As always, a patent application doesn't mean we'll see exactly what's described, but they're a good indicator of what companies are planning for the future.
