The case for bouncers: freedom requires rules and a way to enforce them

Elizabeth Albrycht has a great post on the problem of enforcing good conduct on wikis and other open media –

As we look at the costs of blogs and wikis, in particular, we must build into that some measure of what it is going to cost to make sure that spam, pornography and other unwanted content is kept out. Today, there are technical tools to help you, but none of them are truly foolproof. You will need a person, or team of people, to keep an eye on things. By building the cost of this into the budget for the entire endeavor, you will rapidly come to a decision as to whether it is feasible or not.
