It was said to me the other day:
I only use 1/8th of what the internet is for.
Is the internet really *for* something? Its capable of an unimaginably large number of things and millions and millions of people use it for different things every second of every day; but its purpose?
I think that if you connect to the web and you communicate with someone then you've done all that you're expected to do with the service. All that we should ever be expected to do in fact.
Everything else is a bonus. Everything else is for free.
