There's a new "about" page available here: http://skeptics.stackexchange.com/about
The top bit is editable by moderators. It currently says:
Skeptics is a question and answer site for applying scientific skepticism. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers challenging unreferenced notable claims, pseudoscience and biased results.
What should we write in there?
