No, it is not really a more interesting explanation; I really only use it to serve as an additional flag to signal possible voting rings and sock-puppet activity -- either way sometimes the back-end servers really need or want to know the ip address of the original source. It was mostly random tossed off example of something that might have been mentioned by you in addition to just saying "use nginx as a reverse-proxy." There is nothing wrong with stating this, but I can't see why you think this is something that is not a part of the general knowledge-base of this community. I realize that you want to pimp your blog, but you could have probably chosen something more useful or interesting to the community. At the very least you could have added more content so that the 99% of the community that already knew this would have been able to get something out of this or at least not felt like their time was wasted. At the very least you could have tightened up the headline slightly so that the fact that nginx was the solution to the problem posed was stated in the headline itself.
