My setup is as simple as creating a new text file with the content, using basic markdown syntax to create the post, adding it to git (totally optional), and running a brain dead script to deploy. I could probably teach my mom to post content to my blog in one 30 minute lesson.

This setup could easily scale with the org so that you have tons of people writing content for you. Let them write a post, push it to github, and have some gatekeeper in charge of posting to the site.
