this was a big vocal reason with the fanfest tomes. for some reason some people just didn't spend their tomes for whatever reason - I was waiting to see how many i would get (i.e. they didn't set themselves a clear goal of however many to get in total), or they just plain weren't paying attention to things. there were a multitude of reasons. then of course when the exchange was taken away as it was always set to, people found themselves at a loss because they hadn't paid enough personal attention and thus were left in the dark.
