[Air-l] myspace/orkut/facebook survey questionnaire

All, I am in the process of preparing a survey to be applied online both in the US and in Brazil examining user habits in the use of Myspace, Orkut and Facebook. My primary interests are why are they using the service and what are they doing while they are there.... I would like to see if anyone on the listserv has any suggestions as to ideal questions that should be included. Also, once the survey is online, would it be possible to promote to your students or mailing list you'all are on?
