This is a pattern you see repeated many times, at many levels. Stuff like blogs, HN comments, or just any form of public discourse has a heavy bias (one might say it optimizes) towards people that use it the most. By definition heavy use of such media is time consuming, leaving less time for learning, coding, or doing more productive things in general. So the discourse becomes dominated by not the best and brightest that practice their trade the most, but rather those that talk the most about it.
