I've been looking at the way people are using tags (not XML tags but associating words with text or pictures) and, so far, concluded that some form of focusing mechanism needs to be introduced to limit divergence of tags which leads to the Tower of Babel.
I think one of the weak areas is exposure. Lacking exposure to common tags causes people to invent their own. But exposures out of context contributes little to convergence preceeding emergence.
Hmm. I think I'll wait for the flower to bloom in its own time instead of screaming at it.
