That's why I care less about new structures or tools emerging for the fun of it than making existing ones meet and understand. As a teacher and now as a consultant, my work has always consisted of porting and explaining concepts. It takes time and redundancy for concepts to spread from their first emerging to their wide and full understanding. Either in a single mind or in collective intelligence. Understanding is basically going from complexity to simplicity.
Simplicity is the hardest thing to achieve, since it needs letting down almost everything.
For example Web users and designers at large have not yet understood the simplicity of hyperlinks. We see hypersophisticated technical tools needing plug-in and applets and so on performing basically no more than a simple bunch of well built links. Ontology is too serious a thing to let the ontologists manage it. Maybe they lack tools to do so. Maybe they lack time.
