This document discusses folksonomies, which are classification systems created by users tagging online items. It notes that while tags may be imprecise, ambiguous, or personalized, evidence shows tagging vocabularies converge over time. The author studies tag distributions and finds single-use tags do not dominate. The document considers how to foster better tagging through educating users and improving systems, but recognizes that limiting tags risks losing valuable metadata and the diversity inherent in folksonomies. It concludes the best approach is remaining open-minded and retaining as much user-generated metadata as possible.
