I write political economic reports as a hobby just a neutral slightly cynical take on things. The challenge is finding a platform that doesn’t collect data while also being active and having users interested in these topics. (Mainstream social media is out of the question. No) Platforms i’ve tried : lemmy, mastodon, substuck, writefreely
I’d genuinely suggest self hosting the reports on a site you control (possibly using a CRM that’s self hosted of some sort of hosting service) and then just link it into various places.
As simple as fuck static content webserver can be run on random extra hardware you have lying around or a budget cloud instance and domain names are cheap.
