Not criticism: suggestions. I don’t think any writer can reach his or her potential without a (okay ...) critical reader to say, “That adjective is weak: you can find a better one,” or “Are you sure that’s the exact verb you want?” or “This structure isn’t perfectly clear ... maybe if you broke it up and put this before that?”
Whatever they are — suggestions, criticisms — I value them and they help me grow.
Writers shmiters, you still have the cutest children on the Internet, all of them!
