I think it's a bit short-sighted of a comment you're making. It doesn't need much work to make it simpler, nor to make it more advanced for a developer/designer.
if you look at the blog post again, I added more screenshots of the back end dashboard. The platform is more advanced than you think. Designers can use a server-side markup language to handle custom skinning of web page content & UI, along with half a dozen other advanced core features. complex applications that can be installed, tableless responsive design, editable web design template for every web site with built-in source-code editor, javascript-like server-side/client-side scripting language, 3rd party widgets, google analytics, near-live-editing of web pages, DNS management.
