Ontology is Overrated: Categories, Links, and Tags

This is a great article that discusses what I had thought about a number of years ago when I got involved with taxonomy for a documentation project I was working on. It's a great read for those that use Google and Yahoo and the differences between how they view things so you can find things. But, this was done in a much better fashion than I could have done. Simple put, some things can be easily categorized and have a beginning and an end, other are too free form to be concrete about it.
