[Air-l] question for the list: who coined "talk/write"?

Hi, all, In working on an article about expression emotion online, I remember early on in the literature on online communication, someone used the term "talk/write" to describe online textual communication, whether in chat or email. Understanding that theoretically anyone could put those two words together to describe the tone of much online interaction, especially among friends, I wonder if you know who first used those words in a scholarly book or article? Also, feel free to suggest any other terms or to provide links to those. Thanks much in advance, andee/andrea baker
