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.
You post to a location you control, then post the link to that to other sites.
That way you own and control the content.
There’s a reason why Meta and Twitter hate external links, it takes people out of their feed
Yes, I understand, but half the stuff in the diagram on the website just doesn’t make sense.
Just make an RSS/ATOM feed and be done with it.
