The choice to use folksonomy for organizing information on the Internet is not a simple, straightforward decision, but one with important underlying philosophical issues. Although folksonomy advocates are beginning to correct some linguistic and cultural variations when applying tags, inconsistencies within the folksonomic classification scheme will always persist. There are no right or wrong classification terms in a folksonomic world, and the system can break down when applied to databases of journal articles or dissertations. Folksonomists are confusing cataloging structure with personal opinions and subsequent social bookmarking. These are not the same thing, and they need to be separated.
A traditional classification scheme based on Aristotelian categories yields search results that are more exact. Traditional cataloging can be more time consuming, and is by definition more limiting, but it does result in consistency within its scheme. Folksonomy allows for disparate opinions and the display of multicultural views; however, in the networked world of information retrieval, a display of all views can also lead to a breakdown of the system.
David Weinberger has a counterpoint.
