The people who don't know what that means, are the very people who need to know. And vice versa. It all balances up.
Most people don't believe in reading user manuals. When they get into difficulties, they curse and fume before giving up.
I not only use manuals, I read them BEFORE using the product. Sometimes before even BUYING the product.
For example. Thanks to someone who lives with Albert, we need to get a new TV. As the only techno-competent inhabitant, I've been comparing features on consumer websites. And for more precise information I've downloaded several manuals for competing brands.
But I've had to take deferred gratification to new extremes, even for me. The cellmate has commissioned a piece of built-in furniture to house books and equipment, with a big space for a TV. But once the furniture has been installed, it'll be too late to wire up the TV behind it. So I've got the job of visualizing the length and variety of cables, buying them and bundling them, so the furniture guys can insert them now. All before we even know what kind of TV we'll have.
It's good to remember that these are only first world problems. How fortunate I am really.
