@kev I think what scares many sysadms. like me from opening instance open for registration, is the work associated with moderation, takedown requests and such nontechnical work. I think more federation could helped by making it really easy install a "family" #mastodon server, maybe as a app on #Nextcloud or as a #docker instance. Moderating a small instance with only your friends and family seems more manageable job.
vis.social is an open social platform for creative people, especially anyone in sciArt, data, visualization, creative coding, and related arts and research. English is the common language of the instance.
