He is certainly not spread evenly over all hours of the day and night.
I made a graph out of his "show all posts" page (changed the number in the URL from 15 to 2880). The script only came up with 1189 posts..where on earth the rest are I don't know.
First bar is 0600, last 0500. Times are GMT-6 (in theory).
Personally I wouldn't call that "evenly spread".
Edit: While it only got 1189 posts for him, it got the right amount for others I tried it on.
