Just reacting to the executive summary: where are the tradeoffs? The port decreased memory usage on the client significantly, by how much did the server's burden increase? How have their hosting costs changed now that less work is being offloaded to the clients?
idk they didn’t say, but the server side delta of JSON generation vs HTML generation is small in the overall scheme of things and HTML-style apps tend to be less chatty because they push you towards the one-request-per-view ideal
