Is there a Fediverse service that allows you to only post to a list of people and/or custom group? Facebook has had this for ages but I believe Mastodon doesn't.
Being able to post to custom lists of follows would help me engage with people on here in healthier ways. For example, when venting, I'd love to be able to limit to friends who I trust not to "well, actually" me (or with whom I care enough to repair with if they do). Instead I often just don't post at all.
