The Ann Arbor District Library site is great with the tags - lots of fun playing until I decided to search more constructively and with a specific item in mind. Interesting to see how Yahoo has added the concept of 'the shelf' into its classification. But in all fairness to them, humans generally like pattern and putting things in pigeon holes and like to know where something fits. We spend time with our babies getting them into a 'routine', possibly taken aback when they throw over one routine for another. So - I'm kinda with them on this.
Am I allowed to say that I got bored reading the Shirky article? Sorry!
I have been adding extra tags to my blogs already but will add a few more to today's one..
