I’ve been doing POSSE for a while now and it had helped me immensely by saving time and stress.
Basically every time I post something on a 3rd party site I store the content locally. Currently only in Obsidian and some locally cached videos and articles (TubeArchivist and Raindrop)
When I get dragged to the same argument or topic again, I can just grab my old comment, maybe edit/update it a bit and post it.
For some stuff I have longer blog posts I can link to, for some they are images and graphs.
Feel like the (totally impractical) fediverse end-game would be for each individual to have their own activitypub service, and federation happening on a person-by-person basis. So you retain some control over anything you publish, and your history is yours to keep.
