I haven't thought much about that book until now. I ran across an article about the horrors of the future of advertisements on eBooks. It's a great read and I hope you'll go here to read it (after you finish reading my post and commenting, of course).
What kind of gets me is the title of the article. It is "Kindle at Poseidon's Gate." I've never heard this term used before. All I could really find on Google about Poseidon's Gate is several links to this article and some song by Cybertribe with that title. I can only assume that this allusion means to open Poseidon's gate is to invite a flood of things that you may not particularly care for.
I feel stupid for not having heard it before and am sure that it is a common saying with all of you. Let me know if you've heard it before.
