Most notably, it has been confirmed in many empirical studies on tagging(see e.g. [Golder:2005, Hotho:2006, Cattuto:2006]), that tag distributions tend follow a power law—a small number of tags is used very often, while a very large number of tags occurs very rarely.

This holds true both for individuals as well as whole tagging communities.
