You're right, no doubt. We had been doing a better job picking a "meaty" chapter for the excerpts but lately it looks like we've defaulted to a lot of "chapter 1" selections. I'll see what I can do to remind everyone involved to please try to pick something more representative than chapter 1.
On the other hand, we do know from research that a lot of our readers do like to skim the index. They might have a handful of topics they want to ensure are covered in a book before they buy it. While that may not be the way you browse books before buying, we do know that the indexes are useful to some readers.
