HyperCard should be saved, as well as given a technology boost.
I've noticed that Apple now have a Help Center application, as well as numerous online documents and tutorials to help novice users.
If this client became as ubiquitous as e.g. Acrobat Reader/Quicktime Player then HyperCard could sell a lot authoring tools and allow the client to be downloaded for free.
If Apple incorporated the need for the HyperCard client in the OS - e.g to read online help then it would be a product with a future for sure.
The fundamental ideas that drove the creation of an application like HyperCard still hold true today, companies like MacroMedia make a good living off of them too. MacOS is one of the most media orientated platforms around and it would be a shame to see one of the groundbreaking apps to go the way the dodo just because it may not be seen as 'core business' in the current climate.
