Great summary and some interesting ideas - especially 3x5 cards, no schedule, and structured procrastination.
While I agree with his point on structured procrastination - sometimes the most inspired work is done while avoiding something else - it's also important to balance that with focus. I find my focused procrastination valuable and my scattered procrastination frustrating. Procrastination is rarely productive when it means bouncing between four things (reading HN, hacking on a library, writing a blog post, and buying a book at Amazon).
I find more and more recently I'm not just procrastinating in parallel but generally working in parallel. I'll switch from task to task and keep forgetting what I was doing, go back to a tab and realise I've left something half-done, walk through my office on the way to the toilet and sit down and do the crossword instead... I actually feel like an absent-minded professor!
I can't really figure out why I've started doing this or quite how to stop it; it feels a bit like those Choose Your Own Adventure books where I used to skip ahead to see if certain choices would end up with death, end up with about ten branching paths (I couldn't mark any more than ten pages with fingers!), then collapse the paths one by one. I ultimately do get everything done and marvel at it, but the sheer bamboozlement I face when realising I've "done it again" is getting annoying.

Procrastinate in serial, not parallel.
