So I wake up to greet the Internet with everyone in the comics blog intelligentsia all agog because Lex Luthor stealing forty cakes is now "canon," whatever that can be said to mean. And everyone can't stop wasting valuable ones and zeroes talking about how brilliant and clever it is.
I know it's just a throwaway gag, I know it's just a little extra Easter egg thrown in to please the fifteen--sorry, twelve--fans still left, but honestly, endlessly self-referential stuff like this pushes the audience numbers in one direction and that direction ain't "up."
Jesus, were it not for the Internet, people wouldn't even know what the hell "Lex Luthor stealing forty cakes" thing was all about, so it's a reference to a semi-forgotten DC tie-in book (written, funnily enough for people who didn't read comics, back when we made an effort to achieve such things) that turned into a minor Internet meme that is now a throwaway gag in a comic that exists, if at all, as a head-scratching reference for everyone who doesn't know what the gag's all about.
Comics about other comics, in other words. And while this may seem an innocuous thing, this kind of obsessive "everything is important" stuff ultimately leads to acute and virulent cases wherein you make Element Lad's girlfriend a magic tranny pill addict so he can be canonically gay because look at his goddamn haircut. [NOTE: This actually happened]
Sometimes I wonder if comics haven't already imploded and all that's left is a small handful of people cracking wise and trying hard not to notice. Comics, ladies and gentlemen! We can't seem to create much of anything the masses might want to consume but we're fucking fantastic at contemplating out navels.
