To grasp the meaning of tags (the almighty web link) we need to understand abstact feelings. Businesses don't go there, too scary. They need fewer MBA's and more artists. They need to get REAL PEOPLE - FAST!
Businesses would get better ideas if they used social web tools and social media to engage employees, customers, and partners on a free flowing and unconstrained tagging basis instead of a pre-defined hierarchy of words that define the way things are or should be according to the business.
To get ideas - engage the wisdom of crowds, in ways you've never imagined possible. You can see this idea in action on del.icio.us and technorati.com.
Kathy Sierra from creating passionate users blog remarks on "The wisdom of crowds" ..."the wisdom comes not from the consensus decision of the group, but from the aggregation of the ideas/thoughts/decisions of each individual in the group."
