Global Accessibility Awareness Day is May 9 (facebook.com)

We are launching the first ever Global Accessibility Awareness Day on May 9th.

The idea behind it is to have people who surf the web with assistive devices, show developers and UX/UI people what it is like to navigate the web for them.

You have to understand that there is a problem before you can fix it.

Besides changing the world, an added benefit is that your SEO is likely to be considerably improved.
