While I don't disagree with James/Paizo making money, if they produce products gamers don't value, they won't make much money, will they? I suspect that is why James is following this thread - what people like, and what they don't like, is incredibly valuable intel from a marketing perspective.
As monsters become more complex, maybe the "two page limit" needs to be sacrificed, rather than just presenting a stat block. In addition to, perhaps even more than, flavour text, I like to see tactical information for the monster. So many, especially those with a wide array of abilities, are far less powerful than they should be if the GM does not grasp the synergies of their abilities. Unfortunately, the more abilities (and the more complex they are), the less space is left for tactics, flavour text, etc. AND the more relevant that tactical information is.
Especially where flavour text, etc. is cut for space reasons (ie the work to create it has already been done), maybe it could be made available online in some form. It's a value adder and, while I would not likely want to pay a writer to prepare add-ons for the book (costs for no extra revenue), if the work is already done it seems a shame to toss it - and if it persuades a few more people to buy the book, it may be revenues greater than the incremental cost of putting it online.
