Nerds ( also one myself ) tend to suffer from the over-generalization fallacy. Whereby they think that their local experience generalizes to a much larger scope. For instance, If you read most of HN programming articles with the prefix "when writing code for a web startup" they make sense, if drop that prefix they stop making sense. It also helps to keep in mind that advice that holds in the startup world can be quite toxic when applied elsewhere in the industry.
