(You notice I haven't told you what the invention was yet? I implied a question, and didn't answer it. You're waiting. You're wondering, what did almost no one have in 1980 that almost everyone had in 1990? You're definitely going to read the next paragraph, aren't you? Thus the principle works in a micro sense, as well as in a macro one. Page to page, paragraph to paragraph, line to line – even within single sentences – imply a question first, and then answer it second. The reader learns to chase, and the momentum becomes unstoppable.)
