For years, the Internet’s technical constraints went hand-in-hand with the realities of Internet usage. At first, most people viewed Web pages but did little to create or change them. Web journals, photo sites and video sharing didn’t come until later. Even when users had a need to send information–an email here, a shopping transaction there–the amount of data was small. But as those consumers evolve into contributors and require better upload speeds, many of the old technical constraints remain. Consider DSL services from phone companies.
