Well written article. A good macroscopic look at patterns in tags as exhibited in delicious. Based on a friday-to-sunday crawl in June 05. Sampling is reflects users active at that moment. Perhaps the main finding is that the distribution of tags for a given URL stabilizes à la Polya's urn after about 100 bookmarkings. Also lists 7 kinds of tags, of which one is subjective (qualities like funny) and two are relevant to personal use (self-ref: mycomments; task organizing: toread).

Collaborative tagging describes the process by which many users add metadata in the form of keywords to shared content. Recently, collaborative tagging has grown in popularity on the web, on sites that allow users to tag bookmarks, photographs and other content. In this paper we analyze the structure of collaborative tagging systems as well as their dynamical aspects. Specifically, we discovered regularities in user activity, tag frequencies, kinds of tags used, bursts of popularity in ookmarking and a remarkable stability in the relative proportions of tags within a given url. We also present a dynamical model of collaborative tagging that predicts these stable patterns and relates them to imitation and shared knowledge.
