All that and the Kitchen(Cognitive Heat)sink

I saw a fascinating keynote speech (video, transcript) the other day by Clay Shirky author of Here Comes Everybody where he discusses what he terms cognitive heatsink. Checkout what he as to say about Gin, TV and Wikipedia and where exactly people do find the time. I've been thinking about this speech for a few days now and just the name of the concept really struck home for me and I have it in my notes widget in my Vista sidebar as a constant reminder until I get struck with the next meme to flow through me.

For more on Clay check out Coding Horror's take on him which has a video where Clay discusses some of the concepts in his new book. I especially like how some technology becomes so important to our social interactions that it practically becomes invisible to what we are doing.

If you've seen either or both, what are you thoughts on what Clay talks about?
