Since this is a real life survey, I am looking for the gender of the respondents in real life. About the second thing that you mentioned. The testers of the beta version of this survey were approximately 30 people. None of them mentioned that I should add more answers on the question concerning their age.(8 of them were 30+).As a result I didn't have any feedback about it. About the other issue "how long you have been in SL?". With this quesiton I wanted to know the experience of the residents. In my opinion, someone who has been in SL for more than 2 years, is enough experienced unlike with a new user.
Since the title of survey is cultural, social and technical aspects of SECOND LIFE and not of REAL LIFE obviously I was referring to the gestures and the facial expressions that the avatars perform. The subject of the questionnaire was not about the psychological parameters of the real life of the users. Moreover, in case that I would like to investigate the gestures and facial expressions that performed through a web cam or so; be sure that, this would have been highlighted at the end of the question.
Once again, the survey is conducted in real life. So the questions about Second Life,Facebook and twitter concern the preferences of the users between these virtual environments in real life. Obviously in real life the avatars don't exist. And yes Facebook & Twitter are officially virtual environments:)
Thanks for answering it,
Thanos
PS: once again when you have essentially questions about the questionnaires please contact me.
