The mania has begun... you can't go two minutes without someone going "Hey, did you hear the new Harry Potter book will be out on July 21st? I have to get it as soon as it's out!" Oh the pain...
The book isn't going to be any different whether you get it one day or the next... so what's the big deal, folks? Sure, I'm interested to find out how it's going to end too, but geez. Why don't you just pretend the book will be released on 7/22/2007, order it on Amazon, and when it arrives you'll be like "sweet!"? Then you won't be disappointed. It's like people who set their alarm clock forward 20 minutes so when they ignore it and wake up 20 minutes late they're suddenly right on time. (Which, by the way, I never have understood, because 99% of the people who do this, KNOW that their clock is 20 minutes fast, and intentionally plan that into their day, so it really defeats the purpose.)
Sure, everyone wants to know what's going to happen with Harry Potter... they've been chomping at the bit for the past year just waiting for the finish. Maybe it's a sense of "beating everyone else to it"... so they can be the first on their block to know what happens. In this case, I wouldn't stand a chance regardless because I read slower than two turtles chasing each other across fly paper.
Myself, I plan on just waiting a week until everyone I know have each read it about a dozen times, then I'll borrow it and read it when I get the chance.
