I may be old or disconnected, but it seems like the like of the flash animator community won't be seen again. Where will we find another Homestar Runner or Weebl?

It was the right tool at just the right time. It was well able to deliver animations and interactive multimedia with the one tool and ecosystem. While the JS/HTML5 tools can manage animations and multimedia, it seems like the environment, libraries and tools are much more spread out... which perhaps discourages animators, while developers are used to working in such a way.
