摘要:Information published online can help many vineyard workers better understand concepts that relate to job performance. The eXtension Grape Community of Practice (GCoP) created numerous articles and other content to extend information to their community of interest. Assessing impact of these interactions is difficult; however, using economic models such as opportunity cost could help assign monetary value to each page view. Although it presents an incomplete picture of the impact of the article, deriving the opportunity cost allows authors of online articles to assess how readers value their time and the investment they are willing to make to read online information.
