I've posted my reviews on Amazon and the JavaRanch BunkHouse. As of this posting, neither review has popped, but they should soon. I tried to contain the off-color commentary and bigoted epithets as much as possible.
The Bunkhouse has a 250-word limit for a review. Usually I have to edit my first draft for that. This time I wrote the short one first though, as Amazon was offering the book for pre-order only, and so not accepting reviews. As a result the Amazon review is a bit different, not just more detailed.
Today Amazon has announced it will ship Effective Java starting June 14. If you were lucky enough to attend JavaOne, however, copies were plentiful. I understand they added 2-3 additional signing sessions with Joshua Bloch to cover that demand. That is a programming rock star, friends. If that wouldn't convince you, check the attendance at Bloch's talks. Huge. Might want to take a note for your second edition, Ed Burns.
