Library 2 and Web 2.0

I found the information and discussion on Will Richardson's blog very thought provoking. I agree with the comment that youth using new media often learn from their peers, not teachers or adults. That makes our current curricula less and less relevant. The amount of information is infinite and overwhelming. However, the standardized tests our students are required to take are still based on content.
How do we teach our students to make sense of a much more complex literacy? As adults, we too, need to be cautious of who to trust as authoritative sources. We can no longer be "just readers" we must also "be editors". It is not as much about content anymore as it is about context.
