I got into studying FRP around 3 years ago for my senior project. Aside from a decent, clear explanation, there were hardly any actual implementations of this allegedly good paradigm (something Evan covered in his thesis, and the basis for Elm). It seemed like a paradigm that was full of promise and potential but failed to deliver in any worthwhile way.

(Such was the case for my senior project, studying the viability of Arrowized FRP in Elm. In short, I concluded that it was nothing but hell and nobody should bother.)

I am happy to seem Elm drop FRP, even if I wished it could be the savior of the method. At this point I think it's a troubled concept and should be limited to old theses.
