@Matt Scheurich,

Have you guys tried out Medium? It’s probably one of the originators of a good well-rounded writing UX that integrates rich media and some funky formatting.

No, because that is actually a terrible environment for long-form writing.

Have you tried LyX? That's how it's done. I choose a template and then just write. Nothing "funky," no toolbars wandering in and out, no clicking on buttons to open stuff that should be open in the first place. I can even (and do) use one set of fonts and font sizes to write in, but a different set to publish with.
