2.0 and Counting Icebergs

I was especially interested in Rick Anderson's thoughts on avoiding icebergs in the sea of technology. He voices concerns about practical matters libraries everywhere are facing, such as which print materials should be ordered or reordered in view of the available online options that may replace them. I agree with his view that making library technology more user-friendly will be better for patrons--I also appreciate his use of this older term rather than the retail-based "customers" moniker--than trying to teach each person coming in the door or dialing in or signing on how to use the technology we already have. Technoanxiety exists at many levels, in many degrees, and just as the process of filing taxes can turn some intelligent adults into quivering masses of ectoplasm 'round about April 15th, so can the thought of mastering yet another technological twist. Libraries exist to serve all of the public, not just the technically proficient.
The interactive nature of Web 2.0 is both a great strength and a potential weakness. In an environment where everyone is contributing and few are editing, we have to do our own fact-checking and the question of how to judge our sources becomes crucial. What is factual, what is theoretical, what is opinion or urban legend, what is simply playful? Mr. Anderson's point that libraries no longer have a monopoly on information leads me to ponder how our youngest computer users can be taught ways to evaluate what they see and use online.
