Post-relational databases: What's wrong with web development?

I returned from Varaždin, where first Razmjena Vještina u Varaždinu was held. I decided to present on topic which can be summarized as the right problems from non-relational stack on the web.

I fully understand that presentation is packed with information, and I did skip some angular-mojolicious examples which are documented in README so take a look there also.
