I hate to be the one to tell you this, but it's a marketing blog run by developers. Marketing isn't some specific department certified as containing Marketers by the federal government. It's an activity with a goal to expand the market reach for a product, service, brand, or any other entity.

This is marketing content... And there's nothing wrong with that! We all market ourselves every day of the year. We may not admit to it or realize it, but it's inescapable.
