Twitter!

Twitter has been used by many from around the world for their own purposes, but twitter has no limit to what the users says. Usually, people like to "tweet" what they are doing, for example: famous people like Miley Cyrus, but my teacher uses twitter for professional usage. So there are many uses for Twitter, if used improperly discipline is given accordingly. A general example is a teacher was caught tweeting something unprofessional and was punished.
