A post on 21st Century Learning alerted me to some data reported in BusinessWeek concerning who is doing what online.
I have pulled out the data for read and write activity (read is the higher value). The data are for blogs, web pages, and video. Social networking which some might suggest involves both read and write functions was another category with higher values. Age differences (I realize the numbers are small) show expected pattern and probably somewhat of an interaction (greater difference for production over consumption with increasing age). The raw data were generated by Forrester Research – I will have to see if a more complete account of the survey is available.
