On a similar note, I think people were _way_ too early to celebrate the death of Flash (security issues aside of course). Developers were making content in 2000 which their contemporaries 20 years later don't come anywhere close to in terms of performance, design, or responsiveness.
Flash had more than just security issues. There were definite limits on complexity.
A great example is the original Binding of Isaac; written in flash, but near the end everything was so precarious that backups had to be made before certain publishing stages because sometimes it would corrupt the files it was trying to build (Due to the complexity.)
Well ignoring those issues, is there a html/websocket "framework" which works like flash did?
AFAIK, "zero code" systems still haven't reached the level of hypercard (the spiritual predecessor to flash) when it comes to being able to define event->action with a mouse, much less expanding them to the full capabilities of flash.
