In case you haven't read this already, or if you have and wish to weigh in, Neil Gaiman took the time to answer a fan's email regarding George R.R. Martin and the feeling that GRRM was procrastinating on producing the book.
Neil's thoughts? Well for his thoughts in his words (which I highly recommend), you can find them here: Neil's Journal on GRRM. If applauding a blogger did any amount of good, I would have done so for Neil after reading this. He's right, George isn't working for us, even though we might think that he is. Neil's explanation that purchasing a book or starting a series is not an implicit contract that the author owes the rest of the story on any particular deadline.
Anyway, read his article. It's fantastic. And once you do: what are your thoughts on Neil's take?
