If there was a post on HN that said "I often see people wearing socks over their pants, and this is why you shouldn't wear your socks over your pants", someone might observe "is this a thing? I don't think this is common". Invariably this comment is going to self-select for the extremely uncommon person who wears socks over their pants who will observe that of course, everyone wears socks over their pants.
When people write "people often" or "people often ask" types of blog posts, 99.99% of the time they are basically just projecting their own learning, beliefs, etc. These discussions seldom actually exist, it's super common, etc. That isn't indicative of anything.
