Writers/editors really, really like Wordpress for some reason, which is like 40% of the Internet, add to that all the other Php stuff. At $DAY_JOB we have a Wordpress instance behind our VPN and use the json API to send the articles to a front-end server written in something else. Forces us to duplicate some of the front-end plugin code (and we try to not use many) but we get peace of mind in exchange.
