time for POSSE: post once, share everywhere
About 10 months ago I posted this thread saying that it would be useful for the fediverse to consider post once, share everywhere paradigms: https://lemmy.ml/post/641509
And now we have The Verge writers saying similar things: https://www.theverge.com/2023/10/23/23928550/posse-posting-activitypub-standard-twitter-tumblr-mastodon
Maybe worth re-considering.

I'm not sure I understand how this isn't already possible. Create an account on some federated platform, such as your own self hosted one, and people from any federated platform can now follow you. Isn't that already POSSE?
If I want to post an image to a lemmy instance it only goes to that lemmy instance and that specific lemmy comm. What if I want to post it to mastodon but have it post also to a couple different lemmy comms or on multiple instances or to a pixelfed account? Or what if I want to post to pixelfed but have it automatically show up to my mastodon account? People on mastodon could follow my pixelfed from mastodon but I might not want to force people to follow me twice on mastodon (follow my pixelfed and normal mastodon account).
Facebook has this kind of posse for Instagram and Twitter, tumblr, and fb all used to have posse paradigms in the early days of open API access.
I offered some ideas in my original post about how this posse could be done using hashtag parsing. There's a lot of room for experimentation here. And at some level some of the issues here might be at root ahout the way in which identity in the fediverse isn't properly nomadic/portable etc. The case for this would be less of an issue if identity was decouple from platform and I could have an account that reached across multiple platforms (a single identity for both my pixelfed and mastodon and lemmy accounts. As it stands you have to have a separate account for each to fully interact with them. If the fediverse decoupled identity then one could have a single identity across platforms and that might make it easier to build platforms in a way that were even more interoperable).
I'm not sure why you would need accounts on all those different platforms. Isn't the whole point of posse that you just post it once and then anyone, regardless of platform, can see it? That's what already happens (with the caveat that some, like lemmy, won't show you certain types of posts, like notes).
And people following you on one platform but not another sounds like more of a desire for multiple identities, each one a fragment of your actual identity. That's another concept, that stuff like socialhub try to implement.
