The answer to this depends entirely upon who you're trying to reach with your tech-blog-as-marketing approach. If it's primarily recruitment-oriented marketing, or you're marketing a tech product (apologies, I haven't checked the link - but it's not relevant for this general advice). If it's recruitment-focused or you're a tech provider marketing to technical customers quality is probably more important. The intended audience is educated enough to spot and dismiss fluff outright and anyone that doesn't isn't a recruit or customer you want. If your goal is marketing to non-technical people who buy your product a technical blog is probably irrelevant at best and potentially destructive at worst. If the customer is non-technical and doesn't understand the material you present publicly, they may be scared off. Fluff pieces that demonstrate knowledge with lots of buzzwords that appeal to middle-upper management will be more effective with this audience.
