@write_as fascinating to have the option to turn federation off and on per *user* (rather than per instance). I wonder if this could be made an option in micro-blogging apps like (eg #GNUsocial, #Mastodon), as well as in other federated tools like #Hubzilla and #Friendica? Each user could toggle federation on and off from the POV of their UI, without impacting on what anyone else on the instance can and can't access.
