May 17th is Global Accessibility Awareness Day. See the source link for more. The participate page is a great list of things to test for and be aware of.
The target audience of GAAD is the design, development, usability, and related communities who build, shape, fund and influence technology and its use. While people may be interested in the topic of making technology accessible and usable by persons with disabilities, the reality is that they often do not know how or where to start. Awareness comes first.
