But, The Right Thing doesn't exist yet, and this does. So the question for potential users is whether to take the risk of building a following here (and encouraging followers to migrate from twitter) when it could easily fail in any of the usual ways, within days or months. I don't have an opinion yet :)
@Meaningness I feel pretty torn about this, and also uneasy about this instance's policies w/r/t heterodox thinking

For all users, it's worth checking out the mastodon.social content moderation guidelines, at https://mastodon.social/about/more

As @sonya points out, not everyone may be happy with them.

As our host @Gargron point out, if you don't like them, you can run your own instance.

But instances choose who they peer with... so the Mastodon-based network may balkanize.

I'm starting to think that the right use-case for Mastodon is not as a Twitter alternative (long-term public presence) but as a Slack alternative (private and often short-lived discussion groups, or organizational intranet).

A group is motivated to pay for its own instance so long as it is useful... Who is motivated to operate one as a public service, with years-long commitment?

@meaningness The Slack alternative is #matrix ( https://matrix.org/ ), specifically, https://riot.im/app/ . It federates, and there are bridges to other services, for example I participate on #freenode through it.

@lambadalambda offers an independent #riot instance at https://matrix.heldscal.la/ .
