@mikarv IMO replies and QTs have very different meanings and uses.

A QT is a clear “share with commentary”, which is valuable when sharing info across communities or domains. E.g. explaining why a post on fiction writing has valuable info for academics.

@lowd @jfpuget “copyright images cannot be used without consent from copyright holder” is not true as stated. US copyright law gives a specific set of exclusive rights, and “use” isn’t one of them. The linked resource primarily covers use that involves distributing the original in some form. Fair use & use not covered by law are legal.

This isn’t to defend the models, just that both legality & ethics are subtle. IANAL but have advanced lay knowledge of copyright.

@jenn the 3 big things I think there are to think about in host selection:

1. what are the moderation policies (both formal and in-practice)?
2. what's the local timeline like (is it useful for discovering things relevant to you)?
3. who runs it and do they have sufficient resources and expertise for security updates, continuity of service, etc.?

answering (3) is hard. My personal account is on a host w/ lots of experience, but in practice the server is super slow to propagate content.

@jenn I think sigmoid.social & hci.social are pretty similar in many ways, just different focuses - community-run, just HCI-centered vs. AI-centered. ACM has institutional backing, for whatever that is worth.

I wouldn't bother moving myself, except that scholar.social has defederated from some servers I need my professional presence to be open to, like journa.host where some Idaho journalists have their accounts.
