Lack of accessibility effects your life negatively in a thousand tiny ways every day. For others, the effects are not so tiny and may represent considerable challenges, if not permanent barriers, to participating in modern life.
Accessibility effects everyone. Accessibility is everyone’s responsibility. The sooner we understand this, the sooner we stop seeing accessibility as “someone else’s problem”, the sooner we realise that it is in all of our interests to understand the issues and tackle them in our own products, the sooner we make the world a better place for everyone.
