Controlled and suggested vocabularies: Are tags making us dumb?

Companies like Boeing spend years developing controlled vocabularies to drive ambiguity out of their technical documentation. For example, tech writers might be told to use the word "turn" but not "twist" when describing any circular motion involving a tool. And, at Corbis, the home of millions of digital images, the in-house cataloguers might be told to use the word "shore" and not "beach" when describing coastal photos.

But no one is in a position to write a controlled vocabulary for the Internet, And if they were, you can be sure that many of us would be twisting the night away on the beach, just to break the rules.

This is the promise and the risk of folksonomies. Folksonomies arise when people are tagging objects (Web pages, photos, etc.) in public. If you want something to be found by others, you'll choose the most popular tag. That adds yet more momentum to that tag. And before you know it, most people tag posts about PC Forum as "pcforum05," not "pcf", "pcf05" or "Esther's thang." Folksonomies are bottom-up controlled vocabularies. (Via Joho the Blog)
