I still love really long novels - if they're tightly constructed, which seems to be a rarity these days. Even short novels can be too long, if they meander.
I still love a good fat book as well, but it definitely has to have some *meat* on its bones. I believe it's been mentioned elsewhere here that today's publishers have a pretty tight word count and force most authors to stick to it and for the most part that's a good thing. Just so they never do that to Sharon
