Can DOM elements get their headers streamed before their content? Can we bring back the progressively loading GIF but with state???
I see that as a big potential win for usability. If I knew I was waiting around for 3 seconds to have somebody's twitter feed load, I would simply move on to the part of the content I needed. I DON'T need to see their press releases in full. Maybe the first one...
If state could have relative weight to the user and could be loaded in a smart sort order, we would be able to browse the web with high fidelity when we want, and speed when we don't.
This seems to fit nicely into a personalized web experience, but could just as easily work well for a standard anon user based on aggregated usage habits.
I'm rather inclined to build something like this because I needs it, but if this exists in any form, please lmk where to find it.
