> The key insight into the SPA is that you are writing a coherent client experience.

This is the best way to put it I've yet seen. HN articles keep saying things like "now that navigation transitions are solved in CSS, there's no use case left for SPAs". Is everyone just writing apps for widespread content consumption or something?

> CNN should not be an SPA.

Yes, and we need canonical "that should be an SPA"-type apps to bring up in these discussions--which can be hard, since all the best SPAs are for getting work done, not publishing content for the public to consume. Thus, as a class they tend to be department-procured B2B apps and not as generally recognizable. I propose GMail and Google Docs/Sheets/Slides for starters.

I think the easy answer is "could you see this system being rewritten in QT or Visual Basic 6?"

If this would have been a desktop app in the 90s, it's within this scope.
