Tagging captures the variety and commonalities in thinking about an object. When many people tag a url, it turns out that some of the tags are common, while some are unique. A lot of people, making decisions independently act in an intelligent fashion, and provide value for everyone. Del.icio.us manages to balance the individual’s selfish motivations, and the group good, in a manner I have not seen many social systems do. It’s a delicate balance, but del.icio.us maintains it very well. Let us look into how it maintains that balance, and why I think that the Lazy sheep bookmarklet disturbs it.
Cognitively speaking – just what is happening at the individual level when you tag a url? I encounter an article I would like to bookmark. Semantic networks related to the article are already active in my brain. When I press “post to del.icio.us” it’s not much more work to note down some of the more important associations.
