Hello!
I just bumped into Ghost yesterday, trying to discover its features now.
Maybe someone could help me, I want to build a website, where users can signup/signing, write their own blogs, subscribe to each other, like/comment other posts, is this possible with Ghost? Or it is just for personal blogs?
Thank you in advance.
Intresting. Looking for this. 
Ghost can let members subscribe to your content, as well as letting you invite staff members to write content on your publication. The way you describe your requests sounds like you’re wanting to recreate Medium though, which is a social network with a focus on content publishing.
Ghost is more focused on letting you curate content for your publication
