Realize that the majority (and I'm willing to say probably over 95%) of people today us the internet on their phone. They have a few "apps" which they switch through by swiping left or right (changing channels). The use Facebook, Amazon, their chosen politically aligned news site, Google search, and a few other things. Probably not much more than the 6 channels of TV I had as a kid.

And the Google searches are rarely if ever for anything beyond the first few links or the sponsored content. Really, page 2 and beyond might as well not exist. The users don't go there. Google could just return results from major organizations and users would be fine with it.

I lived through PC era, from start to finish. It took me a long time, but eventually I realized that 99% of the population was never going to understand how computers work. Just the concept of a file and a folder is beyond most people (that's why phones don't have them). Once I gave up on expecting people to learn about computers, computing became much easier. Phones, tablets, and so on, for the masses, the desktop for me. And now I didn't have to go fix peoples screwed up computers - they don't have them anymore.

The importance of a domain name, much less a sub-domain, is now irrelevant. A search result, of of the first few, is what matters. You will never get users to understand a URL.

At one time the internet might have been for us hackers, but that time has passed. It's now the domain of the masses.
