Here's an idea for your knowledge management woes - a knowledge marketplace. We all know it will be sometime before we have a true semantic web so try the hidden collective mind inside the machine or Mechanical Turk from Amazon.
Why do people work for such small amounts that Amazon pays? What's the incentive?
“MTurk is a marketplace where folks who have work meet up with folks who want to do work,” according to Jeff Bezos, Amazon's CEO.
Imagine your organization operating as such a knowledge marketplace - seems like a clear cut incentive to me and the pay is higher!
