The subsite isn't accessible through the dropdown list. I can only get to it via a thread where swcarter (I think) provided a link. Moreover, several sections there link you to the news. (Advantages & Disadvantages, for example.)
The subsite isn't ready for primetime yet. As soon as it's fleshed out and fully ready to go live, I'll be making an announcement about it. The links you've seen so far have just been teasers .
