But the host is not, and many services exist to categorize the content of domains already. What is the statistical difference between innocuous-site-with-every-kind-of-content-ever.com/friendship-is-pornographic and mlp-fip.com? If more sites are like the latter, then HTTPS will only hide which MLP pictures you are looking at, and not that you are looking at MLP porn. And if a site like the former became too large, we'd have to worry about the government issuing secret trace/tap requests against them.
