Moderation systems are a particular subpassion of mine. In the abstract, people can think they sound bland, technical or intimidating, but fundamentally moderation is really about all those parts of an online community that stop it just being a place where people stand and shout randomly at each other. They're about finding the structures and the mechanisms, the techniques and the sensitivities which will help a community form out of a seemingly random clumps of individuals, which will help that community defuse unpleasant situations without killing each other and protect that community from attack.
