It would be wonderful if it were a simple case of secret mailing lists used to attack Wikipedia are evil, secret mailing lists to improve Wikipedia aren't evil, but it's not. I'm more concerned with secret mailing lists intended to improve Wikipedia allowing vast errors of judgment to go unchecked, especially when those lists are populated by respected editors with the ability to seriously damage the project. We know Wikipedia Review have a tendency to be hypocritical but there's nothing we can really do about them.
