I had no idea before reading this article that HyperCard dated back to 1987. It was still being used in my fifth grade classroom in 1996 (I remember it vividly because that was the year I won my county fair's "multimedia" competition with a HyperCard stack!).

As a kid, everyone I knew who liked computers loved HyperCard. It was an amazing learning tool and I still find myself reminiscing about it like the author of the article.
