Jon Udell on Meta Data approaches of apps like FlickR and Del Icio Us. Abandoning Taxon Omy is the first ingredient of success. These systems just use bags of KeyWord-s that draw from - and extend - a flat Name Space. In other words, you tag an item with a list of existing and/or new keywords. Of course, that idea's been around for decades, so what's special about Flickr and del.icio.us? Sometimes a difference in degree becomes a difference in kind. The degree to which these systems bind the assignment of tags to their use - in a tight feedback loop - is that kind of difference. Feed Back is immediate. As soon as you assign a tag to an item, you see the cluster of items carrying the same tag. If that's not what you expected, you're given incentive to change the tag or add another... These systems offer lots of ways to visualize and refine the tag space. (Wiki Word, Touch Graph) Armed with such powerful tools, people can collectively enrich shared data. But will they? The success of Flickr and del.icio.us won't necessarily translate to the Intra Net (Critical Mass). You can import the global-Hive Mind, but you can't export the local-Hive Mind. That asymmetry defines the challenge we face as enterprise knowledge gardeners.
