The Web Accessibility Puzzle…
… has many pieces
• Web developers must understand and practice
• Web authoring tools must make it possible
(and easy) to create accessible content
• Assistive technologies and browsers must
support accessibility standards
• Policy makers must demand accessibility (and
policies must be enforced)
Another important piece…
Just Do It!
Make it accessible
The act of outsourcing tasks, traditionally
performed by an employee or contractor, to
an undefined, large group of people or
community (a crowd), through an open call.
