The power of the internet...always finding a way to really get stuff free. Thanks.
Yes. I'd much rather pay $N than spam my network.
I'm in the same camp on this one.
Actually, the way I see it, if the book is interesting for me to read, then it'll probably be interesting for my friends to read as well. I don't love the tactic, but I don't think it's that bad (assuming I know the book is interesting, and not a completely speculative thing).
That's the only reason I keep my facebook account... it's a dumping ground for competition entries and free content
