> 9 times out of 10 it is Apache httpd, and numerous instances of it at that.

A lot of your post is not wrong, but that statistic is just not right at all. Less that half of the time we see apache instances behind NGINX, and it's mostly because it's legacy, and hard to move away from it. The other half of the time it's application specific web servers, or other NGINX instances.

Of course, as someone who works for NGINX I would guess you would see more nginx behind nginx. Based on discussions with people who do Apache httpd support as well as what I've personally seen, 90% isn't that far off the mark. People like using httpd for dynamic content. A lot.
