Really, extending the todo.txt todo-list format (http://todotxt.org) to being a blog platform is as simple as having a heredoc style delimiter for each post. Then of course, you're just recreatin org-mode from first principles.

Social media is also merely the exchange of plain text and media files.

If only we had a simple and free platform that had the following features:

   * Supports multiple simultaneous users
   * Has simple user and group access control
   * Treats everything as a sharable file
   * Easy for admins to securely deploy out of the box
   * Easy for users to securely connect out of the box
   * Uses few enough resources that it can be ran on effectively any computer, no matter how powerful.

If only we had such a mythical system, we could decentralize the net. If.

I don't understand all those features you're asking for, but maybe some adaptation of https://fossil-scm.org ? It's a wiki, blog, DVCS, and bug tracker all in one program, using sqlite as a backing store. An instance of it runs in about around 2MB of memory on a small vps.

That's an old video promoting Unix, so I don't see what you're getting at. Unix is not a distributed OS. The web has to work over communications channels with fairly high latency, so you don't want a file-system-like interface either. If you have something specific in mind, maybe you could say what it is instead of being coy.
