Like the time feedback in soundcloud.com. There could exist something similar for text. Here the idea is to make it easy for the reader to respond to your writing. They could do this by scoring individual key sentences or paragraphs. Here they don’t need to write exactly what is wrong with the sentence. They could just score it based on their feeling. Say a score zero to ten from strongly disagree to agree. It would be interesting to see what you could do with the collected results. I assume some misunderstandings could be cleared up. The advantage is that the readers could participate in the creation of the text even when the author don’t want to handle bad comments.
