I'm a little tired of J.K. Rowling's smoke-n-mirrors marketing gimics.
Dude, just write the book (and allow your editor ample time to edit) and then sell it.
All these stupid little games and hints about more people dying just wear me out

In other news, Chana has a great post about Snape. (And I completely agree with her!)
You should go read it, and re-think your Snape prejudices!

And, as long as we're on the topic of Harry Potter - I believe the missing horcrux is in The Order of the Pheonix's headquarters. (Do you remember in book 5 when they're cleaning out the junk in the old house? And the twins find something that won't open???)

Ponder that this holiday season!
