Extraordinarily well said, in today’s Social tagging in the enterprise:
…the tagging craze is mainly fueled by social effects. It’s true that I tag my own content online in order to help me keep track of it, but I’d be unlikely to do so if I were the only person engaged in that process. Categorizing my stuff to help other people find it is part of the motivation, but it runs deeper than that. Observing who else bookmarks my items, and what terms those folks use to describe my items, helps me measure the effect of my work. Finding other items those folks have bookmarked and tagged leads me to new resources relevant to my work.
