As a media specialist I love to praise and lampoon wikipedia. I keep my copy of the Tibet page with me listed as the kingto prove my point. Unfortunately, as I also point out to classes, the edits were deleted within 5 minutes. I like to point to the value of community developed knowledge, the power of the group effort, but also the messiness of the group effort. People in a democratic society don't always make the best choices and sometimes people take advantage of the weaknesses of the democratic framework. My district's media curriculum has a key understanding that reads "I understand the value of an intellectual work in a democratic society." That would be uniquely hard to do in a district that tries to maintain a wall that blocks out all miseducation. But block wikipedia...c'mon. You're going to have to turn off all of the tubes for this to work there is way too much to block. Perhaps schools should set firewalls that block all internet traffic and then allow only trusted websites in from a database. That seems a reasonable response. While we are at it, perhaps we should live in gated communities that check the character of everyone that we come in contact with.
