Doesn't make sense. "N" does not pick out the beginning of any word. If you chance across the tag, your interpretation is less obvious than,
"... Too Long; Do Not Read"
The contraction makes sense, and thus the natural transformation into a meta-informative suggestion makes sense. Contractions serve to convey information, usually engendering more intimate dialogue. So it also invites the question of "why not"? And we all know how that goes. It invites the author and really any reader to a game not dissimilar to trolling, usually. It may not take a position necessarily, in terms of the message, and this is not required of what I am saying; however, an explanation of why one would post it at all stands in order. I think the conveying of information to other readers is also important.
