OP here and I agree with your assessment of the Pavlina blog's change over the past year. His earlier stuff was great but I've had a hard time digesting some of his newer topics.

I posted this because there was a lot of interesting discussion on the Matt Mullenweg post in regards to his sleeping patterns.

My lifestyle would make it hard for me to try polyphasic sleep, but I could see where it would help my productivity if I could pull it off.
