The problem Pemerton ran into right out the gate here is that for simple functionality, he had to use a definition of a term for what he was talking about out the gate. But the word choice suffers from the curse of almost all word choice in such things; it has semantic loading beyond its literal meaning or even the specific definition he provides. So people are going to, to one degree or another, react to it on that level (specifically the premise that some play styles provide it better than others) and that's going to fog the ability to have the discussion.
That's always going to be a problem, as any attempt to separate denotational from connotational meanings is, outside of very narrow contexts (which are essentially impossible to produce in a forum thread) a doomed enterprise.
