This is kinda neat, as it shows how to use a plugin to generate a site and then commit the output to git for deployment elsewhere (unfortunately, GitHub-centric). Similar to Hardypress, using WordPress as a static site generator.
I prefer goHugo for static sites, but it is interesting to consider using WordPress on a local computer, maybe in a specialized VM, to generate a complex site… but then again goHugo is a single binary, so…
