For some reason this article received a fair amount of negative feedback here. I quite enjoyed it.

It's good to remind developers that they should ensure that their products degrade gracefully, and to give a few examples of what could go wrong. Mentioning the (somewhat basic, but still generally effective) fault-tolerance of HTML/CSS vs JS along with the user's basic viewpoint also helps to get his point across further.

Maybe I'm just used to reading longer form content, but I didn't feel that this brief blog post was a waste of time.
