In reply to Jeff Chandler.

My reason for wanting to use Markdown was because HTML editor (text view) for WP seemed overly complex. Markdown simplified that. Visual editor didn't seem like it would be able to handle what HTML/Markdown delivers. Now it does. The alternative writing method (Markdown) seems far less necessary to me at this point. But I comment here because I'm open to the idea that perhaps I'm overlooking something that Markdown provides that visual editor (in 3.9) cannot deliver.
