This is fascinating but to read the series is it $8/mo? I’m confused, that is more than most magazine subscriptions.
Maybe something like Kindle's system that has some kind page-read/engagement metric against the monthly revenue pool.
Maybe something where I get discounting for buying in bulk. 10 newsletters for the price of 5 a la carte or whatever, and I can allocate my "newsletter credits" at will, even switching between them.
Also how can libraries and other institutions subscribe and delegate their access?
