I've evaluated what they are doing on their technical merit. If you want me to give you a detailed explanation of why I prefer their system, it'd probably take about an hour, so it's a bit much as a HN comment.
I genuinely think their direction with the API I'm using is the way forward, I've been waiting for someone to have the balls to do it for some time.
Any anyway, I must have missed the outpouring of love Google received for closing Reader, for not having a native Google Linux kernel OS Drive client, and so on.
