This should be a lot more obvious to the tech crowd than it is. I suppose it's the familiarity effect (see https://xkcd.com/2501/)--what's obvious to us isn't necessarily obvious to most people, and we heavily undercount the degree to which confusion-of-basic-things exist because it's second nature to us.

And we are talking even more basic than most people on HN can imagine.

Such as:

"Is your device turned on?"

"Are you logged into the site and not just searching google for the thing your want our application to do?"

"Have you actually purchased our product and not a competitor's you just think is similar?"
