The communication of knowledge and ideas is intrinsic to the human condition. Our earliest ancestors had a rich oral tradition, through which they passed on what they knew about the world, often across great distances. Our systems of communication have evolved and matured, from those oral traditions to the earliest cuneiform writings and all the way up through books and newspapers, to radio and television. With the advent of the modern age and Al Gore’s gift of the Internet, we’re now able to share our knowledge, ideas, and lots and lots of cute pictures of cats, around the world in less time than it has taken me to write this sentence.
