The problem is, these ironies and meta-ironies are just as old, trite, tiring, and grating as the same thing meant seriously. Believe me, meta-irony on this topic has been done before, many times, and not only based on the irony of an xkcd comic.

It might be the first time you do this, and you think it's funny, clever, and 'meta-ironic' (oooh). I suppose it's somewhat like lists of jokes that people forward around: funny the first few times, and "I'm going to auto-killfile this" after a few years of hearing the same ones.
