"As computers have become more powerful and taken ever greater roles in
our daily lives, the way we have used them to communicate with others
has grown and evolved. For many of us, we started out with email, and
then as people began to spend more and more time in front of their
computer, we shifted to instant messaging. Communication through text
has disadvantages, however, and so numerous solutions have appeared to
make the act of web-based communication more personal."
