@Sarah: Thanks for the write up. I had heard about the Ghost Kickstarter project and was just wondering what had happened to it. Is it bad that I have never heard of nodeJS? Going by what @AndreasNurbo said, it seems to be more complicated to setup compared to WP's PHP+mySQL combo. I must do some more reading up.

Great interview though - it was informative to be able to 'listen in' on the thoughts and decision processes of John and Hannah. And then to see how their work has effectively influenced the WP-sphere.
