Tannen's text on gender and conversational interaction seeks to present research into gender differences in conversation as evidenced by direct speech data. The first section is comprised of data about friendship rapport, focusing on "girl talk" (Eder and Eckert, respectively) and storytelling among men and women (Johnstone).  The second part focuses on "conflict talk" both among children at school (Sheldon and Goodwin, respectively) and adults (Brown).  The third section becomes more theoretical as it attempts to rethink the nature of discourse in terms of power vs. solidarity (Tannen) and turn taking (Edelsky).  Finally, James and Clarke review the literature and attempt to reframe the discussion of conversational interruptions among men and women.  While none of this research deals with online communications, I believe that  such analyses can be extrapolated to apply to online discussions both as "female talk" and "conflict talk".

Tannen writes from the perspective that there are key, quantifiable differences in men's and women's speech from a sociolinguistic perspective which can be applied to workplace communication.  Although this book was written for a general non-academic audience, it can offer some interesting theories of spoken language and gender and power in an office environment, which arguably could be extended to email or electronic communications on the job.  Chapter 2 deals with conversational rituals that take place on the job: routines such as apologizing, giving criticism, ritual fighting, compliments, and complaints.  Chapter 2 discusses "Indirectness at Work" and how indirect speech can be viewed as both powerless and powerful depending upon the gender of the speakers and listeners.  In my experience, such rituals and directness/indirectness are key features in gendered speech found both in real-time verbal speech and in written internet venues.
