Here is an interesting essay by Gary North: "Wikipedia and Google Will Bring Down Establishments All Over the World." A couple of quotes:
Soon, brains and insight will rule, not bank accounts and official accreditation by state licensing bureaus. The Establishments will all be in defensive mode.
The gatekeepers can no longer control the flow of information. This has never happened in man's history. Gatekeepers still control the gates. But the walls have holes in them. These holes are widening.
In short, if you find something evil that wobbles, push it.
