Twittering Brains

Our resident cyborg passed along this amazing new development: using brainwaves to send text messages via Twitter. Now, at one level this seems almost nightmarishly trivial, using advanced brain-interface technology to allow idiots to bore us with their lives more than they do already. But consider the case of people with severe spinal damage or other conditions which prevent them from communicating by speech or sign language. A brainwave interface holds incredible potential for them -- they can Twitter, in a few years it may let them talk, it could someday even allow them to control mechanical limbs.
