Today, the web accessibility community have been getting frustrated with a comment Ian Hickson wrote in reply to a bug report ‘No alternative text description for video key frame’ in HTML5.
Ian Hickson is the
author of the HTML5 specification and has been known as an advocate of web standards. For me, web standards also includes accessibility and I think this is why we are disappointed with his question:

“I’m confused. Why would you (a blind user) want to know what the poster frame is? How does it affect you?”
Steve Faulkner has nailed this one on the head with his reply:

“Vision impairment is not binary, people are not either totally without sight or have 20/20 vision, there are may gardiations. a good proportion of people who are categorised as ‘legally blind’ have some vision, but rely on a screen reader for the majority of their interaction with web content, when they see a fuzzy blobs on an image whether it be a video poster frame or on a canvas or an image, the provision of a text alternative may well be useful in helping them make sense of what those blobs are.
Also why wouldn’t a blind user want to know?”
It’s an excellent response and it remains to be seen if it is sufficient argument for Ian Hickson.
