How is this different than Math Overflow (http://mathoverflow.net/) which is another Stack Exchange site?

The difference between the two communities is the level they require to participate.

From the MathOverflow FAQ: MathOverflow's primary goal is for users to ask and answer research level math questions

From the Math Stack Exchange FAQ: Math Stack Exchange is for people studying math at any level & professionals in related fields
