Why be Skeptical? Why be Secular?
Micheal Bigelow will be giving a talk this month about his experience with the Guerrilla Skepticism Movement on Wikipedia.
The mission of the Guerrilla Skepticism is to improve skeptical content on Wikipedia. They do this by improving pages of skeptic spokespeople, providing noteworthy citations, and removing the 'unsourced' claims from paranormal and pseudo-scientific pages. Why? Because evidence is cool. They train and they mentor.
It's great way to make a contribution to the skeptical movement - especially if you speak Mandarin.
