There's a lot of legitimate criticism, but they're also a noticeable amount of "reply guy"-ism (pedantry that can sometimes derail the conversation and bring nothing of substance) and "pet peeve syndrome" (people who'll always repeat the same criticisms of a product or company even if completely off-topic for a submission). It would probably be hard to classify them. And whenever I go on reddit I see that both are enormously worse on there.
