@Gargron Why is that a bad thing?
I would guess that it's a bad thing because, in practice, this means most people crossposting are on Twitter and have zero intention of engaging with people on Mastodon where they're cross-posting to. So they're just dumping filler into the ecosystem, which isn't good for the health of the community as a place for living breathing human beings intent on interacting with each other.
Yeah, I think for your use case that's perfectly fine and we're all benefiting.
But I would add to that, that there's so much noise on Twitter already, that they're not necessarily harmed by cross-posting. And Mastodon, to a large degree, depends on the quality of interaction here, so it needs the signal-to-noise ratio to be pretty strong. And you're definitely part of the solution there, but not these other cross-posting folks.
@jeroenpraat @abbenm @Gargron seems reasonable.
