Disclaimer: I am no Statistics master but I'm passionate about Statistics, I'll try my 2 cents on this.
In hindsight, I think I should have reordered the values on the horizontal axis by weekdays, Mon-Sun. If I did so, we would have seen that diagram as some sort of distribution looking like the Gaussian distribution, with the center on Friday. With that in mind, I'd say it's natural that people spend more time on HN during the weekend and that it's only natural that people are inclined to post here on those days. So my opinion is that more posts appear on HN during the weekend, so the probability that a popular post appears on these days is greater than any other day. Still, that's just my rambling and I'd be super happy to hear some other opinions.
