Pros
Pro Posts can have multiple authors and user management in general is very good
Ghost has arguably done what many other CMS have tried and failed. It has one of the, if not the best user management features out of the box. Posts can have multiple authors and every user can have a well defined role. This makes ghost perfect for large multi-author online magazines or blogs.
Pro Ghost(Pro), the official hosted version of ghost is very customizable
Ghost provides a simple way to deploy and develop a blog or news site using the ghost platform. It allows you to host it on their site with everything ready and configured, but unlike other CMSs which do the same, ghost provides more something like a hosting environment instead of a massive multi-site install.
Pro Ghost is very easy to use for beginners
Ghost was built to be a simple and fast blogging platform. There are countless themes in the theme marketplace, both paid and free which can be installed. Everything unnecessary was stripped away and only the most important things like SEO, social sharing and other plugins were installed right into the core. This results in very little configuration and makes ghost the easiest CMS out there.
Pro Great admin dashboard
Ghost's admin dashboard is one of the most beautifully designed out there. By removing unnecessary plugins and by adding them directly to the core ghost application, the dashboard is very minimalistic, displaying only the most useful data, such as social data or analytics and other important data that any blogger or developer needs.
Cons
Con Although ghost has mobile support, it still lacks in it as it does not have a mobile native app
Ghost has a decent mobile web app that works through the browser only, at least for now. While it is good, it still is not as good as a native mobile app. So in that regard, ghost still has way to go.
Con Although very simple to use, it's simplicity can be hindering
It's very easy to add content and customize themes or find free or paid themes for ghost. But that's it, it's very easy to use but also so simple it's simplicity can be underwhelming. It can be frustrating to try and tackle ghost's limitations.
