I have 530 non-patron followers, it would be amazing if I could create posts that are only visible to them. These are people clearly interested in my stuff (to some degree), being able to target them seems useful.
I can achieve the same effect now by blasting everyone with a public post, but that means I either have to annoy my existing patrons with “Sign up!” call to action that doesn’t apply to them, or I have to be less targeted in my messaging so it’s less of a call to action. Targeted = win.
I see it like selectable tiers, but with options for all non-Patrons (people who stumble on the stuff in the feed), or only non-Patron followers.
Unlike Patron-only posts, nothing blurred out should be visible to Patrons (since that would create a perverse incentive to stop being a Patron so they can see it).
