Armour’s "The Business of Software" column ("Counting Boulders and Measuring Mountains," Jan. 2006) was based on good ideas, many of them were overshadowed by errors and omissions that made it difficult to understand what he was getting at.

Clustering Versus Faceted Categories For Information Exploration
