This is surprising as most of the great novels have come in under 100k (Ender's Game, Gemmell, The Golden Compass etc.) due to focus. To be honest, most of the books I find irritating are the bloated epics written today. Even George R.R. Martin is trying my patience on many levels. My fantasy novel is just under 100k, but more happens in it than has happened in perhaps the whole series of Wheel of Time. While a long novel can be great provided there is enough story to merit its length, I find the minimum length rule arbitrary and reactive rather than rational. Flash forward three months when a couple best sellers are under 100k and we'll get a new cue card in the mail.
I say this with respect, but there are plenty of reasons the publishing world is behind the curve. Perhaps someday there will be a system in place that enables a more efficient and accurate assessment of the many manuscripts lining people's desks. I have ideas, but I'm sure others have proposed the same measures. However, the world works as it does, and we as authors must do the best we can. It's easy for many to say "write a great story and it will fall into place", but this is false in today's random publishing environment. Supply exceeds demand (due in part to modern publishing practices and marketing geeks) and people are seeking what "sells" rather than good writing (they are often exclusive, let's be honest). In the end we can only write the best novel we can and polish it to the point where we feel proud of what we've produced. From there, it is up to fate and whimsy and current trend analysis--complete with pie charts and technicolor.
Though, who says that isn't enough? The best part about writing is the journey and the sense of discovery, I feel. Chasing the carrot on the stick ultimately doesn't make one more satisfied because ambition bites the nails of success. And then writing (for expectation) becomes artifice, not art.
