For those who are new to the SE 2.0 format, proposed sites go through a "Definition" phase where sample questions are posted by interested users to give an idea of what the site will be like. These questions are then voted on, but each person is limited to five votes total.
The current sample questions are taken from mathoverflow and MSE, but this is not necessary. In fact, the new site would best benefit from professional mathematicians in applied areas posting sample questions that they would actually ask each other about mathematical modeling.
Also, if you think the proposed site is silly, leave a comment.
