I did read the link, but i'm not sure how to interpret it, it just mentions that the word application can have several uses. Which, ok it does, but it doesn't sound like it was contradicting anything i wrote about "applications" not being just about specific types of software like productivity or even a subset of "programs" (the GEM manual even shows how it was used in the opposite where an application can be made up of multiple programs).
In any case, I've also said it was a bit of a fuzzy term and it feels like we're ostensibly arguing similar points.
