The Web is fundamentally designed to work for
all
people, whatever their hardware, software,
language, culture, location, or physical or mental
ability. When the Web meets this goal, it is
accessible to people with a diverse range of
hearing
,
movement
,
sight
, and
cognitive
ability.

– Aaron Gustafson (Foreword in:
Sarah Horton. “A Web for Everyone.”)
“On the web, every decision I make can have a
profound effect on hundreds of thousands (if not
millions) of people’s lives. I can make checking into
a flight a breeze, or I can make it a living hell.
That’s a lot of power. And to quote Stan Lee: ‘With
great power comes great responsibility.
’”
