Questions appropriate for a Stack Exchange-style Q&A are on topic for Mathematics SE and MathOverflow. If you would like to experiment with this type of content on MathOverflow, great; butit might be something you can try; but unfortunately, we are not currently accepting proposals for new sites whose core premise is to solicit critique, reviews, or other types of discussion — See http://discuss.area51.stackexchange.com/questions/24050/announcement-sites-soliciting-reviews-recommendations-comparisons-collaborat. Sorry about the confusion.
