I disagree with the article's premise. As someone already said, Holmes is a celebrity within the show's universe, so it's quite logical to suppose there are obsessives in that world and for the writer to play with that. The fact that he's also teasing real world fans as well only adds to it.
The same has already been done in the revived Doctor Who as early as the first episode, "Rose", and several times since in both RTD's and SM's eras.
Anyone who was totally unfamiliar with either show would have struggled a little bit with the Christmas and New Year episodes. How would someone who didn't know Sherlock had faked his death or that the Doctor was on his last regeneration have faired? Quite well actually. The Sherlock episode spent a lot of time giving that backstory because it was integral to the main part of the story - his reuniting with Watson and it's consequences. The Time of the Doctor took the opposite approach and spent very little time explaining the last regeneration and other dangling plot threads. They were not particularly significant to this episode's story and were explained away in a few lines of exposition from Matt's Doctor.
