Controlled Vocabularies Cut Off the Long Tail

Controlled Vocabularies Cut Off the Long Tail is an excellent article by Joshua Porter that discusses an interesting property of folksonomies – the long tail.

The Long Tail paradigm is about the discovery of information, not just the finding of it. The distinction I’m making here between discovery and finding is that users who discover information didn’t need to know it was there to begin with, and so couldn’t have been trying to find it. In a word: serendipity.
