And the terms of the presentation of the software agree well with my own conclusions:
Apparently many of the comments on the first part, especially on Hacker News, come from the old guard ;)
The dashboard is built as a web or mobile application: it fits in a single page while Wordpress uses principles of desktop applications inherited from legacy with a multitude of tab each dedicated to one of the management task of the site.
The creation of a post makes use of two panels: on the left, the "source code", which is not in HTML but markdown instead. And on the right content as seen by the reader.
This choice is justified by the desire to build a simple CMS, limited to blogging, what was Wordpress at the origin. This reduces formatting problems. It is often difficulty to get what we want with the WordPress editor (TinyMCE) because it has its own rules and removes the tags that are inserted when it does not suit it. This is something that is inherent in all these online editors which do not have the capacity of DreamWeaver of synchronization between the source and the display. The markdown has limitations, but its simplicity provides the synchronization to write a post more comfortably.
Access to prior articles and editing them in Ghost is also facilitated by a double window. A list can be scrolled in a window to select a post and to edit it. It is easy to switch from one to another. Wordpress due to its old design, requires moving from one page to another for the same tasks which makes editing more difficult.
Themes and plugins without templates
There is no reason to meet these compatibility issues with both other plugins and with new versions of the software, which fulfill Wordpress forums of complaints. Once the software has a modern design based on WebSocket like Advanced Explorer on this site, modules can communicate through messages and the same controls receiving the same answers, different modules can evolve independently without inconvenience .
Running on mobile
To access the dashboard on a mobile, we should at least has the offline mode to store all the necessary code locally. But this is not possible with a software written in PHP .
All shared hosting do not support Node.js. But there are such as Gandi. And there is the cloud.
