I have limited experience with nginx, but I believe points 12+13 are technically incorrect -- sites/virtual hosts can be configured in the /etc/nginx/conf.d directory or directly in the main nginx.conf file, not only in the sites-available/sites-enabled directories, as is implied. This makes the conclusions of point 19 and others incorrect. I don't think it necessarily disproves the conclusions of the document, but it calls into question if the author knows nginx as well as he claims to. Id be happy to be corrected if I'm wrong.
