This article explores the emerging folksonomic order revealed by Tag, a key application of Web 2.0. Foucault pointed out in his book The Order of Things that different ways of classification will create different senses of order, which involves not only the order of things, but also the formulation of power/knowledge relation. This paper first explores the historical contexts where the modern taxonomy was developed and its characteristics. The operational procedures of tagging are then described to demonstrate how information is presented and interconnected in such a technology. Finally, the paper explicates the effect of empiricism and dc-hierarchy in the age of folksonomy and the intersubjective relationship between human beings and technologies.
