The hilarious thing is that not only do we, the staff, tank these comments because we see them minute irritants at best, we are likely the target of several times as many. Who better to shake your fist at than the law of the land, even if said law is just a collection of otherwise normal users akin to yourself, yes?
Vzearr is right that this is not worthy of formal retort. Even a warning is not warranted, especially as (most) of the comment is indeed intended to be constructive criticism. If you were not seeking criticism, one would not post questions about such things.
Some elements of the post should be nicer, as if these paltry offenses stack up indefinitely they certainly can and do result in action being taken. But one off unkind comments aren't considered serious enough to warrant action, least we ban every user on the forum for not walking on eggshells all day long.
I'll also post in the thread, however, telling him to remember our first rule: be polite.
