I found this quote on tagging on the following blog: blog4educators.blogspot.com/2008/01/tagging.html
"I strongly believe that all good social systems need to serve the individual motive. Tagging works because it strikes a balance between the individual and social. It serves the individual motive of remembering, and forms a ad-hoc social groups around it. If you are designing a tagging system you need to understand how it serves the individual and what sort of social formations it supports."
Tagging is a great way to:
- Share knowledge
- Collaborate across locations
- Leverage knowledge by search once
