No need to ask permission to quote me, but thanks for asking anyways. I definitely agree that shifting focus towards industrial use cases is what we need.
I guess it's more difficult than shifting the focus towards industrial use cases. Industrial use cases are a great thing, but it is something that the industry has to provide :-) (we tried to do something like that for F# here: http://manning.com/petricek2 (sorry for a shameless plug!)).
But many people contributing to functional programming (in one way or another) are in academia. They are not the best people to contribute industrial case studies - but I think there is still a lot to be done there too! The nice thing about the FRP paper is that it is really just a fun (and very simple and somewhat impractical) example, but it is nice inspiration showing (what was back then) a novel use of functional programming. Some of the more recent academic work around FP lacks this kind of creativity...
