CSS is amazing, but the HTML DOM isn't. It's just so heavy. Maybe if JSON or some similar format could replace HTML/XML, it could be made lighter? Better, I think, would be to use a human readable format like Eno. It's as terse but much easier to read than JSON.
Storytelling seems to underlie all media. Video production, music composition, writing. Whether for a bland, fact-based documentary or an animated cartoon, all these artistic tasks involve a process of storytelling. We must create the optimal experience for storytelling through software, remembering even this process of building software is one of storytelling. We know the resolution, the creation of a software that best facilitates storytelling. Working toward that goal, we should consider all we do, even these very words, as key to success. If we begin building with the focus on storytelling through written language, we can later add elements to handle specifics such as audio and video meanwhile providing an encompassing base capable of dealing with every conflict.
