I dunno...
I'll admit there is a lot of cliffhangers (Jon Snow's kinda pissed me off as well) but it's really just the way the guy writes. I didn't think it degraded the book that much really (again, with the exception of Jon's story) and saying it was bad is like saying he shouldn't write the way he writes and honestly I think he's just a fantastic writer so...
Yeah Bleck, you're right. There are more cliffhangers in Dance than the previous books but fuck; it's a really big project and I think the only short coming is that he takes way too fucking long to bring on more of the story.
