Test Your "Usability" Knowledge

In honour of World Usability Day, recognized this year on the 12th of November, I am inviting you, for the entire month, to test your knowledge around usability, and how it pertains to blind and partially sighted consumers.
 
Organizations' awareness and participation around World Usability Day events have increased considerably, thus further supporting its purpose... to promote, explore, and ensure the usability of everyday products/services (hint, hint).
 
In keeping with the "usability" theme, every quiz submitted before November 30th is automatically entered into a draw for a free, accessible iPod Shuffle, usable by way of its unique VoiceOver feature.     
 
So, once you've had a chance to review the contest details, have fun testing your usability knowledge... good luck!
