I suppose it may be in part down to the fact that Brooker seems a fairly Internet-savvy chap. If he can find unofficial uploads of Screenwipe on YouTube* and display them in a later episode, thus creating a confusing recursion for those also watching that later episode on YouTube, he can probably find your story in which he, say, has sex with himself from another dimension or embarks upon an uncomfortable relationship with David Mitchell, and then he will review it scathingly on something called Internetwipe and you will have no choice but to abandon the Internet and cry.

See, now I want you to write fic, and put it up somewhere, just so some anonymous person can make a Charlie Brooker-type comment on it and leave you completely confused.
