I have seen a number of statistics on the fact that people use e-mail more often than any other online resource. While reports on the time and places spent on web are plentiful, what I haven't found are studies on the average amount of user time spent reading and/or replying to e-mail (or other forms non- web browsing of Internet activity.) How much _time_ does an average U.S. (or other country) Net user spend using e-mail at home or work? How much time does an average worker with Net access spend on personal e-mail versus work e-mail during work hours? What are the difference between different age groups and other demographic factors? On a typical at-home or work computer screen, what window is on top and for what amount of time is each top window being used? Neilsen says that home Internet users average 12 hours a month on the web <http://pm.netratings.com/nnpm/owa/NRpublicreports.usagemonthly> and at-work users 27 hours in December 2002. I wonder how much of this "web" time is actually being spent on web-based e-mail? Finally, are there studies on what people do with their e-mail? What kind of e-mails do people actually read, reply to, delete, forward, save/file, print, etc.? I have seen some studies on opt-in e-mail newsletters click-throughs <http://www.doubleclick.com/us/knowledge/trend/email.asp>, is there anything on related e-mail topics from academia?
