I bought the book for $10 also. Yes it does cut into the author's profits, but tech book authors generally don't write motivated for making a lot of money :-) Rather, the advantages are sharing knowledge and meeting a lot of cool people. I have written several books, and writing is a pathway to meeting interesting people.

Agreed! :)

Out of interest, why not just self publish on the net avoiding the whole money angle altogether? Is there another advantage in going down that route if it basically doesn't pay?
