Is There a Substack Model?

There must be dissident voices who have a general identification with the left, right? I mean, i know that t glen greenwald, he does a lot of stuff on rumble, but he has a substack. Maybe that's the future, that each individual has his own thing. It seems like there's got to be room for some kind of network that can be built. Just so much darned work, and takes so much money.
