Agreed light on the text but incredible story. HyperCard was my introduction to "programming" and I always have fond memories of it when reading related stories. :)
HyperCard was my first serious programming environment as well. There was something about that program running on a Mac that just made the whole system feel "right".
I really believe HyperCard should have been burned into the ROM of every Mac back then, just like Integer BASIC and AppleSoft BASIC were.
HyperCard was the last gasp of Woz's Apple, the respectable one that made tools for human beings. Jobs' Apple prefers selling appliances to consumers, which spelled doom for things that empower them.
