While I am inclined to agree with Crichton's take now, given have things have panned out, I don't think it's as bad as laid out. For one thing, it's astonishing how not-online many people are, even younger people. Sites like Twitter or Youtube are really only frequented by a very small part of the population. I know someone who tries to stay informed about current events but still thinks reddit is "too far out there" to visit.

Since you mentioned accents, I work for a company in the US south/south east. I mostly work with small and local businesses. When I need to contact a company I either speak to a low level employee, like a receptionist, or the owner. Almost always I am greeted by a southern accent. The lower level employees I know are younger than myself and the owners I know are older. These are the not-online regular people. I don't know where they get their news from, if they bother to check at all, but they are certainly not part of the internet hive-mind. So there is still hope. And we have a large reach, covering many rural areas as well as most large cities in the south.

An interesting thing about the company I work for, even as new and re-opening jobs are almost entirely work from home, we only hire people in our region. As it was said to me "someone from New Jersey would have no idea how to handle these interactions" The company explicitly understands there is a cultural, regional component.

From what I've heard the Great Plains region is also doing the same thing, keeping business local and not expanding beyond their region to keep that "homey" feeling.
