The very first time someone reads something they never read before. With regard to technical documentation and dictionary definitions in this industry, first-time readers are even more neglected than first-time users of actual applications. The text is rarely "tested" by people actually reading the material, who have no knowledge of the concept being explained.You Are the ExpertUnlike first-time users of software, who often feel they are not expert enough to evaluate an application, when it comes to reading a technical explanation in the English language, users are indeed experts. As a first-time reader of every definition in this encyclopedia, you are expert in evaluating what you read. If the explanation was clear, our goal was met; namely that it makes sense without having to re-read it over and over. See first-time user and RTFM.
