That is hardly the point. A post can be excellent but also controversial, in which case it is only reasonable to reply to people's comments.
What's actually interesting is the reaction to it. Why such vitriol regarding the OP's being new (or obviously not) or whether he's replied? Why does this cause any "effect" with Charlie and yourself at all? The poster has been around, at least in some capacity, since 2013; had something to say; and said it.
Ain't that enough?
