We had a "professionalism" class in my CS undergrad program. A day using the web with a screen reader would do wonders, I think, for awareness of the issue.
I'm extending a standing offer to come in and give a guest lecture on accessibility, focusing on blind and low-vision users, for any university or high school in the Seattle metro area, free of charge. I've done this a few times already. My presentation would have a mix of concepts, demos (both good and bad), and practical advice. My email is in my profile if anyone is interested.
Have you done this or could you do this as a video or audio that’s posted online and available to anyone? That’d help thousands of people.
If you have any links to your lectures online, please share them. It could perhaps be a “Tell HN” post here (I’m not entirely sure if that’d violate the guidelines).
