Citizendium, the “expert-led, public participatory, wiki-based project to sum up human knowledge” is now open for business. They have roughly a thousand articles on tap at this point and will presumably increase that count regularly over time. There’s nothing on law, yet, that I could see, so the field’s wide open, people. They need editors and authors; signing up is easy.
