Perhaps hidden/unknown to many, but hcommons.social and other instances running the Hometown version of Mastodon, have the ability to post only to their local community and specifically not federate their content to the broader Fediverse. In the posting interface, click on the link icon and choose whether you want to allow your post greater reach or stay only within your community. This can be a helpful affordance for having smaller/restricted conversations. #FediTips
