I don't know about that. I've written a story where it's impossible not to be conscious that you are reading a story, and that was a deliberate choice on my part. Some stories function best artistically if they keep their audience off-balance and at some distance.The last thing an author should be doing is reminding the reader that he's reading a novel.
But there is a difference between an author who purposely reminds the reader that they are reading a novel for artistic effect and one who pulls the reader out of the story with clumsy in-jokes that serve no real purpose other than to show how "clever" the author is.
