I have a theory that IT is split into "doers", i.e. the people who do things, and "talkers", i.e. the people who talk about doing things. By definition, you hear from the talkers more, perhaps because the doers are too busy actually doing things, and to your point there are times when the talkers can sound dismissive of the doers, for whatever reason. But in HN's defence, you do hear more from actual doers here than perhaps anywhere else.
