Great news
Hypercard was brilliant. There were numerous studies done on how non-programmers were bale to develop really useful little stacks in very little time, but somehow that leap to what was called "end user computing" never quite materialised - development became more entrenched and specialised (except for that one block in Accounts who discovered, then "developed" everything in terrifying and broken Access - I am sure every el Reg reader knows one....)
After Jobs canned Hypercard, there was an attempt at a Windows based alternative called Supercard, if I recall, and Oracle bought and badged it as OracleCard. But it didn't have the utility of Hypercard, as they thought of Hypercard not so much as a generalised if inefficient applications environment as a database frontend. Another problem was cost - several hundred quid for a not really great product. In the Free Software world, there was a half hearted attempt with Pythoncard, which again missed the boat, this time thinking that the development environment was the key.
Hypercard's many inefficiencies, generalised nature and small but genuine barrier to entry was what gave it its power - its warts gave it its beauty. It even had a sort of pseudo object-oriented way of drag n drop working if you wanted to push definitions.
As an aside, I have often wondered what a hypercard on RaspberryPi would have done for the education space, where they have done wonders with scratch and teaching python. The understandable English of Hypertalk, almost like pseudo-code. would be more inclusive than the overt codiness even of python, opening creativity to yet more, and surely creativity was one of the things that attracts about technology in the first place.
