@lrreynolds thanks! The point I will make is that VC-backed Substack invests a lot of money in marketing / creating the illusion that it's the only easy publishing platform out there. Ghost actually provides a free moving service and Beehiiv has a media collective to help indie journalists.
Personally I wouldn't use a service that also hosts the likes of Milo Yiannopoulos, Naomi Wolf and countless other problematic publications.
