I received this invitation today through email from administration at college. They want to inform me that there is a event happening there which will be all about usability in modern technology.

The invitation was sent out as a single huge JPEG file and the text in the email contained no information on what is shown on the image. This may have no impact on me, but it reduces usability (and of course accessibility) for sight impaired persons in a dramatic way!

Image that was sent out to advertise the event

Big funky images only are no appropriate way to advertise an event focused on usability, thus you FAIL "World Usability Day"!
