Anonymous blog comments, vapid video pranks and lightweight mash-ups may seem trivial and harmless, but as a whole, this widespread practice of fragmentary, impersonal communication has demeaned personal interaction.
The wisdom of crowds works when the crowd is choosing the price of an ox, when there's a single numeric average. But if it's a design or something that matters, the decision is made by committee, and that's crap. You want people and groups who are able to think thoughts before they share.

If there's any object in human experience that's a precedent for what a computer should be like, it's a musical instrument: a device where you can explore a huge range of possibilities through an interface that connects your mind and your body, allowing you to be emotionally authentic and expressive.
