Harnessing the collective wisdom of the crowd always sounds so good in theory, but few do it really well. More important, few have figured out the best ways to do it inside the walls of a corporation. I was surprised a couple weeks ago when the head of our HR department forwarded a job description to several of us to help her fill: It was for a company-wide Wiki manager -- not the "manager" role that makes it run and administers it, but the kind that evangelizes it, gets people to use it, and finds interesting threads and knowledge developing from it. I hope this is a new trend in corporate intelligence mining. On a related note, I talked to Paul Plushckell, CEO of Spigit, a company creating some interesting social network tools for the businesses.
