The tease paragraphs used on every news site always feel “mean” to me in some way. The text fades out, or it cuts off mid-sentence.
If there was a bespoke intro+conclusion that actually communicated something valuable, I would reach for the Apple Pay button to drop 3$ for the added context and analysis.
Could even have a little marker in the full article, a little past the full fat intro: “Single Article subscribers should start reading here”
There’s no easy solutions though, I’m not going to pretend that works, even if I would like that.
