I'm newly putting some of my writings behind a paywall in Medium, but that doesn't prevent non-members from reading my stuff. In fact, I'm not a member myself yet.
Members are the ones who get to reward the best readings, i.e. writers, which is like parents getting to bias their subscriptions in favor of the talents they most appreciate. Their feedback regarding articles is more what matters.
Which brings up the question: will students under no restrictions w/r to credits i.e. will students with effectively unlimited access, be prevented from accessing the bird feeders?
Parents outside the subscription system might benefit just as much from what the bird feeders teach, with or without any subscription.
That might be a good way to promote the full API.
Would-be subscribers see there's lots of quality behind the paywall, and realize their students' access to other stuff could be contingent upon at least appreciating what's here. The family might agree to try the experiment, for a month at least.
That sounds like the right role for a parent. They want their kids to experience what they consider to be quality content. They get a metric they trust.
As you know, I'm all about wanting kids to know about the Bucky Fuller concentric hierarchy of polyhedrons (obscure topic! -- but why?) which is exactly what I'm writing about on Medium.
Parents in my camp (perhaps newly recruited) will be better better positioned to reward me and my ilk, should they agree their kids would / could / should benefit from what I offer.
