Also you have clearly missed the point of the subject matter. Typing "/thread" is a shorthand response, explaining it with an essay seems rather redundant, hence the use of "TL:DR" as comedy.
I've not missed any point, I merely answered someone's question. Typing TL:DR when I merely attempted to be helpful, is not only rude and uncalled for, but since the reply - long or otherwise - was not directed at you, is also an unnecessary disphemism.
