I read the article prior to seeing it shared here. My conclusion was that it's just sampling bias. Of course you will hear proportionally more of "great" developers if they share more about themselves. And of course those are the ones you'll invite to a podcast. I don't even know what kind of statistical basis they want to put their claims on. A better title would be "the great developers that you hear from a lot share a lot". They make an effort not to promote "share your knowledge on SO" strongly, but it's one of the two actionable thoughts any developer reading this would have. "I should write blog posts" or "I should answer questions on SO".
