Basically looks like the wordpress.com site in a frame. And there is one thing that needs to improve, something that needs to change also in the mobile app (iPhone, iPad and possibly in Android too): Integration.
Yes, wordpress needs to integrate with the system, WordPress is by many people used as a CMS more than a blogging system. Many “news” sites use wordpress, maybe they do need to enter to the desktop/web app to write all that stuff, but others use wordpress as a simple blog system.
