I hate to break it to you, but ASOIAF is a story, it's not a series of stories. It's one story split into a series of books, and GRRM sold those books to readers on the inherent understanding that any author of a series does on the basis that the story would be added too and eventually concluded in a timely fashion, and as highlighted in my earlier post, GRRM was pretty prompt at turning out the books up until he got involved with the hardcore fandom.
But we haven't paid for those future stories and there was no time frame put on future instalments when past ones were released. In one of the responses to the Gaiman post the writer uses the analogy of a restaurant, but at a restaurant there is a timeframe that you can reasonably expect your meal to be delivered to you in. That's not the case with novels. Buying the previous books doesn't enter you into a legal agreement where you get the follow ups within a certain window. I'd love Winds of Winter to come out ASAP but "we made you rich" makes it seem like people think Martin needs to be devoting his every waking moment to writing Winds of Winter. It's an attitude to him that I see online no matter what he does.
How dare GRRM watch football, he should be writing The Winds of Winter.
How dare GRRM attend a convention, he should be writing The Winds of Winter.
How dare GRRM work on Wild Cards with his friends, he should be writing The Winds of Winter.
The release schedule slowing down has coincided with the story becoming a lot more complex. A Storm of Swords blew up a lot of the power structures within that world and AFFC and ADWD are about examining what happens in the wake of that. With the following two books Martin has to figure out a way to answer the criticisms of the fantasy genre he has been making within the series. If you are going to talk about things like how ruling is a lot more difficult than stories make out then your own story needs to have some kind of resolution that works through that. Writing isn't as straight forward a process as "he wrote this much in this amount of time previously so therefore he should have been able to write this much since then"
Claiming it's because Martin now engages with the fan community is a bizarre theory. He's always done that. He's always gone to conventions, taken part in meet ups and done Q&As, both online and in person. He's actually doing that stuff less now. I'm not a fan of Elio and Linda but they aren't the reason the output of the series has slowed down.
It's also worth reiterating that Martin is still actively working on Winds of Winter he's not just fucking about doing nothing. I get that people are mad over The Princess & The Queen, The Rogue Prince, The World of Ice & Fire and Fire & Blood are being released before TWOW but they are just adapted from his already existing notes so he's not creating these totally from scratch and neglecting TWOW. Also perhaps working on these projects is part of his overall process for developing TWOW, we've already seen how elements and themes from Dunk & Egg have played into ASOIAF.
Really? The Gaiman apology? Are people still trotting that weaksauce wankery out?

When GRRM does eventually die (probably at a con from one too many fan jobs) I like to think that Gaiman from his ivory tower of mediocrity looks back upon his words with some degree of self-awareness (unlikely I know) and realises that it was largely through his ill-considered endorsement that we got things like this: -
Yeh, let's just keep speculating on how this guy is going to die because he's not doing the thing we want him to. That's not at all weird. If that situation were to happen I also very much doubt Gaiman would look back and think "damn, if only Martin hadn't spent his life doing what he wanted we could have had another book"
Apologies, I don't know what the picture of him with Ernest Cline is from so I can't comment on that.
