There are other technologies that can carry more complex, detailed messages. There are other delivery systems that are easier to use, less limited in scope and arguably far more secure.

Anyone who thinks it is useful only for spotty, awkward teenagers with a lamentable grasp on grammar and punctuation is living in an ivory tower.
