However, I'm not a Wordpress, or even a dynamic CMS, user. For most of my sites I use a static site generator called Nikola . Creating (or finding) a Nikola plugin to crosspost content would probably be quite straightforward, but where possible I prefer software-agnostic solutions (not least because not all of my sites are using Nikola).
