nil, I know people think networking was the reason HyperCard lost but I think “right click to view source” is the real reason the web won. Being able to edit source in any text editor is hugely important. And I say this as a lover of HyperCard when I had access to it at school but at home I had a 486 my parents went into debt to get us so html it was. Turned out ok in the end obviously but I still wish HyperCard had won. I guess I am spending a lot of time living in imaginary timelines this weekend.
