One of these days I'm going to write up a piece about the difference between responses, reviews, criticism, and critiques.

(Short form: response = personal reaction. Review = attempt to inform potential readership. Criticism = academic. Critique = fodder for revision.)

ETA: hit "post" too fast. My reason for doing this would be to say all four of those things have their purpose; they're only bad when one masquerades as another.
