I tried a quick experiment and got an interesting picture, so today I spent another hour and made the map clickable, and slightly better laid out. The result is interesting, and here it is. Quite effective. You can also see Paul Graham Essays Ranking. The rankings are encoded here in the colour of the different boxes - it's a challenge to work out what the colours mean! One colour plane is controlled by the forward "Page Rank" value, one colour plane by the reverse "Page Rank" value, and the last is always "fully on." Who knows what the various mixes might mean.

Then we compute the likelihood of being on any given page. Finally, I've made a second, smaller map of those essays that aren't linking in with the giant component.
