HyperNext, HyperStudio, LiveCode, and SuperCard are all available and based on the Hypercard model, which is at least mentioned in passing in the article (but not the post, above). When I RTFA, I noted the author states: "All of (the programs based on the Hypercard model) are failures for the same reason: they insist on being more capable, more complexity-laden than HyperCard". Wow, adding more features and making programs more capable makes them a failure? Uh, no. In fact, Hyperstudio is really just an updated clone of Hypercard with lots of color and multimedia features added. The fact is that the Hypercard model had its place as an education tool, but was not that useful for most applications. The article, and the person who posted it here are not really talking about Hypercard, their rant is more a platform to spread conspiracy theories and Apple bashing, which is fine, enjoy yourself, but call it what it is.
