I like reviewers and I like readers.

I support book bloggers in their thoughtful work, and I am very opposed to any authors ever taking offense at a review. That's not an author's place, and demonstrates remarkable immaturity.
Book bloggers are fundamentally "readers who care" -- and I love to have active, engaged readers -- even if (and especially if) they are finding weaknesses and focused on improving books! Yay for book bloggers!
