This thread is a good example of why Adamant doesn't actively solicit reviews. If we get them, we're happy about it, and grateful, but generally too many reviewers are going into it with pre-existing biases which make you wonder why they were reviewing product in the first place, beyond getting a freebie.
Given the fact that we haven't noticed any discernable impact on sales from reviews, we generally prefer that our reviews come from customers...at least that way, the review can tell us whether somebody who was interested in purchasing the product got what they wanted out of it.
Reviewing short PDFs when you personally don't like short PDFs seems....well, odd.
