The critical piece is running a stand-alone environment that has low friction for the users - my family. I want my Significant other to be able to post as easily as Facebook. My parents to browse easily on their devices, and uploading pictures from my phone to be Facebook Simple. Mastodon is pretty close to having all of this if you turn off Federation, other than not being able to run a fully private node. You can still access public pages for users. On my list to check out are: HumHub & Hubzilla.
