AN ARTICLE ON RECEIVING AND EVALUATING FEEDBACK

An excellent article on receiving feedback.  One thing I would add is that as a writer, you have to know what you are trying to achieve with your script.  If you don't know, it's almost impossible to be able tell which feedback will help and which won't.  Without knowing what you are trying to achieve, you can't evaluate the feedback.
