Authority and expertise in a networked culture... it's not a new problem. "Wisdom of the crowd"/ collective intelligence vs. individual genius? Sifting through all the dross, all the ideology, all the self-promotion, and all the poorly composed media.
Yes, all that. My students are talking about it as we read Dan Gillmor's We the Media. But I'm also picking up on a conversation from Will Richardson and over on the Britannica Blog (raise your hand if you're surprised about skepticism regarding Web 2.0 on the "Britannica Blog").
Undoubtedly one of the major challenges as we move into a networked media culture is negotiating the avalanche of information that we must deal with. Some of that information is important only in a short-term and personal context, like a text message or phone call. Much of the information we deal with is only valuable in the narrow context of family, friends, or colleagues. Other media relates to particular personal or professional interests/concerns. Still more is of a broader cultural but short term value, like daily news. Only a relatively small portion of information we deal with is valuable in a broad, cultural context and reasonably long-term. It's this last type of knowledge that is really at stake in this debate at Britannica. And while it's nice to be able to look up what meerkats eat when my daughter asks me (they're mostly insectivores, btw), that type of knowledge is not useful in my finding out what I need to buy at the store or where I can get the cheapest flight to my next conference or even what books I might want to consider ordering for my courses next semester.
