In a previous essay, I wrote about the cognitive aspect of tagging - describing how people tag, and why they find it easy. There is another, equally important aspect of tagging that I did not touch upon - the "why" of tagging. Why do people tag? For many, tagging is for sharing their own information and watching others. Even if you tag mostly to remember your own stuff, it is difficult to remain untouched by the presence of others. This article will explore how tagging lets us connect with others.(1)

Interestingly, the daily expert definitions and the Web2.0 spoof sites (Web 2.0 validator and Web 2.0 or not) attempt to do what tagging systems do not - put boundaries around the concept in a more definitive manner.(2)
This highlights both the strength and weakness of tagging. On the one hand, tagging allows social coordination never forces a decision, so you can reach a tagging frenzy even if the concept is ultimately rejected.
Finally, writing this piece reminded me how much I admire good designers. It took me a while to gain clarity regarding how tagging works on a social level and a cognitive level. And I am simply deconstructing. What came before are the people who dreamt this up in their minds. Hats off to them (once I buy a hat that is ;->).
