This is an idea I came up with as a way to provide people with constructive criticism. Basically I'm oing to try doing this idea.
There would be a group of users, who can agree to help critique other's stories, poems, or story parts (Ex: Chapters, sections, etc.) Then people would submit the stories they would want to have critique on. The critics would then post on the section what they thought about what they were criticising, and post it publicly along with a rating.
This way a writer may recieve constructive criticism from multiple sources with multiple views and tastes which would make these critiques unbiased.
