@PsyChuan This is also why I've never really got on with crossposting - every social network is different. If you're just blasting out the same stuff everywhere regardless, you're not actually part of any of them - they're just loudspeakers you're placing in their spaces.
Even more baffling were the Twitter->LJ imports, which only included that person's halves of any conversation, which.. seemed supremely pointless, TBH. Even if they'd been complete, what's the point? That's from somewhere else, and isn't anything we can join in.
All of your toot goes even more for Masto, where the lack of ads and timeline agorithms, and actual moderation, means it really does wind up being a significantly different space to corporate media - people show much more of their real selves. But in order to know that for oneself, you do need to dive in - you won't know or feel it just making a single toot and then wondering why your world hasn't changed.
