It's all relative. I've met many people who assumed that HN was 90% or more in the Bay Area, and that they—being located elsewhere—were part of a tiny outlier minority. That kind of misperception skews one's view, and I think tends to make people more defensive. They feel like they're up against some supermajority that actually doesn't exist.
That seems like a pretty big number to this user who lives in Charlottesville, Virginia.
