... based on my experience of the incredible usefulness of the StackExchange sites Math StackExchange and MathOverflow, I think this site could become a great resource.
Another site to follow? Oh my! But if it's a good place to get our math ed questions answered, I'm all for it.
Stackexchange will only start up a new site if 200 people have committed to it. This site is 85% of the way there. (I was number 171.) If you want to help make this site a reality, click here.
