Your position is the other extreme. Martin isn't "poor" by any means. He's experienced success at a level most writers will only dream of. Any hassles he gets from fans disappointed fans--the "losers" who provided him with financial security--is more than compensated for by the perks of being a bestselling author and having actualized his personal dreams. Quantitatively speaking, celebrities are amongst the least deserving of pity.
While I know of GRRM, I'm not familiar with Ice and Fire.
Is it a bunch of stand alone self-contained books, or is there an ongoing story that - and this is the important part - has yet to be completed?
Personally, I think he should finish the darn book already.
Book 1: 1996.
Book 2: 1998.
Book 3: 2000.
Book 4: 2005.
Book 5: 2009?
4-5 years between books is too much to expect your fans to wait and still expect them to be your fans...
I've moved on.I'm fine with it.
I don't care if the guy sleeps on a solid gold mattress or a piece of cardboard under a bridge . . . . he's an artist, not a machine whose purpose is to crank out fiction upon demand. He's also human, and doesn't deserve that level of hassle.
A machine to crank out fiction upon demand? He's a writer. It's his job. If for some reason I stop doing my job, I expect those to whom I had made a commitment to be rather upset (and probably demand some kind of compensation). By starting a fantasy series, Martin has a commitment to his fans, especially the ones who evidently like his books* enough to hang out on his message boards (and presumably evangelize his books to others) to end it in a timely and quality manner.
*Quick Note: I don't like Martin's books, and I don't understand why so many people do. So I don't have a whole lot of personal investment in whether or not Song of Ice and Fire gets finished; I just think people should do their jobs.
