So I guess there was a discussion about Wikipedia at the Chronicle, captured in this comment. Marc Meola responds, For the folks who say all sources have errors, that's true but it's impractical to ask people to be critical of and to fact check everything." It's this sort of thinking that leads people to trust "authoritative sources" and to then be led down the garden path. It may be inconvenient, but there is no alternative to fact-checking -- hasn't Iraq at least taught us that? Well, that plus "never get involved in a land war in Asia."
