Medium seems to be going down that path by focusing on delivering true wysiwyg editing on an online service while removing a lot of the bells and whistles that Wordpress and other platforms have.
While this is certainly interesting and exciting, I wonder whether it won't make this too impressive for the casual blogger or writer. With Medium, it seems like you won't be able to rely on anything else than the simple power of words. But then again, it might be the intention: getting the best storytellers excited about the platform rather than an attempt to democratize publishing?
