Ghost is a powerful publishing platform that can be used to build from simple blog sites to complex web magazines.
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 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.
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.
