"I feel like your average user who needs this type of functionality can create it with categories and sub categories and the one who doesn't feel fulfilled by that functionality can go out and find a plugin that make the process of creating CPTs and custom taxonomies easy. Like: https://wordpress.org/plugins/... . The real problem is that CPTs are handled as discrete display units with potentially different templates, you're going to need a dev to make those, one way or another." - Aram Zucker-Scharff

"BuddyPress with some plugin to act as a plugin gateway maybe?" - Aram Zucker-Scharff

"The social media component can be done with https://wordpress.org/plugins... as for the redirect issue, there's a lot of things that will do something like what you're asking. That said, I'm going to recommend you try out PressForward, which will let you collect posts, turn them into drafts and handle the redirect for you. But I'm biased on that, because I'm the dev behind PressForward." - Aram Zucker-Scharff
