Yes indeedy. Those ad.s appear at the top of the page (and elsewhere, but there's *always* one at the top). We're rigorously trained every day to ignore stuff at the top of the page that doesn't look like what we expected. Maybe he should try a bar across the *middle* of the window, or a diagonal, or alpha-blend a red overcast onto the entire page.... Still, it's another technology-intractable problem. If people cared, they would train themselves to look for trouble indicators, like scanning the dashboard from time to time for problems with speed, fuel, temperature, etc. We're trained to operate motor vehicles, but not to operate browsers or MUAs. ("It's intuitive!" Not.) And meanwhile the world is training us that it is vitally important to our sanity and the defense of our time to learn to detect and ignore things that we don't care about. I think that technology can't help this as much as would knowing why we want some technology. People who feel a need will look for tools to deal with it; people who feel no need will ignore the finest tools. -- Mark H.
