The interface is bad on iPad. I can't zoom the text. It's stressing to read with so small text. Reading to the end, the back button makes you skip back through all the pages.
This guy is not doing what he says people should do. He uses the latest fancy web page UX where he should use a well proven UX but maybe boring. Do what he say not what he does.
That's what he is talking about though - he used node.js and redis on a production site when neither are close to production ready. Thanks to him though, both are improving rapidly and should be production ready before long, so kudos.
His whole article is about "woops, going with the latest tech wasn't such a good idea - here is what you can learn from this".
So yes, he is using the latest fancy web page UX and he has written an article about what he has learned. Next site he makes will probably be using well proven UX.
