Two of the online communities I read frequently are currently embroiled in controversy (must be something in the water).
At WheelchairJunkie, it’s inappropriate religious proselytizing. At the braintalk.org MS Forum, it’s the moderators’ attempts to cut down on vast amounts of off-topic posting.
Tom Coates’ blog Everything in Moderation is about creative ways to manage online communities – it looks to have some very useful information. Found via Simon Willison.
