I have no interest in subscribing to a publisher and letting them choose what I read. Give me a way to tell an author I'd like to see more by deciding how much I want to donate to that author after reading a piece ... an instant, secure, online donation. They can put my on their mail-list. If the author chooses to congregate with other authors on a publisher's site, and pay them rent, their choice. So long as there's no paywall.
