This is a project I worked on to make a web application where you could add your work to a database and have it be commented, critiqued, and submitted for discussion on not only the piece, but the critique that it was in.  It also allows the user to rate their own work, along with the viewer to rate it as well. It graphs these ratings, from worthless/worthwhile, positive/negative.  Some other features include adding your transcribed critiques to create a weighted list, such as on 'mbeasl' under the piece portrait of an artist, you can click on weighted list and see what words came up most on the particular critique.
