Agreement around here is so vanishingly rare that perhaps I should celebrate it.
But I'll just say this: The survey was not time consuming. It will surely fail if too few people take it. Those who wish to make an informed judgment about it should pick a book, devote a few minutes to the questions, and decide for themselves. There are pleasures involved in thinking again about a book you really like.
And the best way to improve a survey design is to complain to the designers.
