When I first started building websites, the proposition was quite basic: take content, which may or may not be stored in some form of database, and deliver it to people's browsers as HTML pages.

Often though we fail to reflect on the greater picture of connectivity and contexts the audience of our work might find themselves in. Even a short glance at the state of the World Wide Web shows that we haven’t been building with empathy, situation variability awareness, let alone performance in mind.
