Definitely not just a promotion. We're a mission-driven company and a we've explicitly chosen as a company to share our learnings with folks (even if it reduces our competitive edge a tiny bit) because we believe it's important to good. Not quite open source, but maybe open knowledge?

And while it's nowhere near peer-reviewed academic paper quality (we won't be submitting to Nature or NIPS anytime soon), my personal background is ML — everything we write is backed by cold, hard internal data and we try to stick to the facts.

All of that said, yes, people really like our data-driven insights and it does drive traffic. :)
