I notice that most of Slashdot appears to be anti-McMillan, and not anti-Amazon (surprise). For a different perspective on the issue, everyone should read the post by Tobias Buckell on the matter. In short, he is a midlist author, and he talks about his experience with the eBook market. He has seen negligible differences when his books are given away from free versus when they are charged for, and the lower price points are not enough to cover the costs (which he outlines) to go to market.
Agree, disagree, it is helpful to read a perspective from the other side.
Do not meddle in the affairs of troff, for it is subtle and quick to anger.
