Speaking as the author of the map, that's just an example of my particular social media information flow. Everyone will have a different one. Some notes:
- there is a branch to the right with white boxes that shows some content types that may be applicable for others that I don't use myself (e.g. music) - the map is only version 0.3.1 so far from finished. The node to the bottom left shows some of the things I still have left to add.
