This post has been through several revisions whilst I temper my anger!
A common e-mail from myself to some of the people that I have helped build web sites starts something like this....
"Very disappointed!!! I spent ages making your web site accessible to all. I spent ages showing you why it was important to make your web site accessible. I showed you web sites that didn't have any alt tags for images and how unusable that made your site. I showed you how easy it was to at the very minimum give an image an alt tag. And what do you do as soon as my back is turned...."
The web was meant to be read, not squished.
This isn't the way to test a responsive design.
