Take a look at the SkepticWiki – a new online Encyclopedia of Science and Critical Thinking. It is an additional source for skeptical information that currently contains over 250 articles.
Being a “Wiki” means anyone can contribute. The only restriction is that you have to register as an author, to avoid the obvious risks of vandalism. As this project is relatively new, there are many subjects still to be covered, and possibly much to be added to existing subjects. New contributions are being actively sought so if you have something to contribute, and have the time, pile on in. All they request is that you start with the SkepticWiki for Beginners page to learn formats and etiquette. I would also recommend looking at the SkepticWiki Forum to see what is being discussed, and to post suggestions for any new subjects.
One area I thought needed a little amending was the astrology page, especially:
The first objection to astrology, from a scientific point of view, is that it offers no theory which can make testable predictions, and thus is unfalsifiable
Regular readers will know astrology does make testable predictions. The thing is: astrology’s predictions fail when tested and so astrology has been falsified. If I had the time I’d pile in and amend it myself, but I’m spending too much time online with this blog as it is; if I started on the Wiki I’d never get outside! Anyway, if you’ve always wanted to write something skeptical on the web, but don’t want the work of a whole blog, here’s your chance.
