Unfortunately the larger network providers, which provide access to the
bulk of the users haven't quite grasped this model, or are ignoring it.
Some have jumped the fence and are working with content companies and/or
their providers' to both (a) spread the load out and (b) focus on keeping
content local within a region.
The Internet is made up of users, the users are there in part, because
they believe they can get better, quicker, or easier access to "content,"
than they could using other methods (e.g. newspaper, TV, etc.)
This illustrates the point that if there isn't any content, what is the
Internet but a big Email network?
