[apatters]

I think what Substack is doing is really exciting, but it remains to be seen how large this phenomenon will become. I heard on a CNBC interview that there are only about 30 writers who make a living income from Substack right now (don't know if it's true or not).

"Pay money to support the creator" can work - Patreon is doing around $50M in revenue annually. Bundling can obviously also work with many big and established examples. But it strikes me that the two models attract a very different customer, so those who subscribe to a specific Substack newsletter may or may not be enthusiastic about buying a big bundle of them down the line.
