molilyI'm glad more people are getting into progressive enhancement. Still, as someone who's deep into it, this leaves me puzzled for several reasons. I think we need realistic, non-trivial examples regarding PE & JS. Here we have a rather contrived example with one button/interaction. Not saying it has no educational value. It addresses many practical questions. Yet it's not particularly convincing. One could question this particular example or its implementation, but this would be pointless.
