Dear Sam:
That is a very wise thing to do... In re-reading your website posting I find that you have a target audience that you are looking to survey or discover what they think about...
I feel that what you should do if your looking for a particular survey is just what you are contemplating on doing and you will have a targeted point of view of age 30 and under...
However, you work your venture - best of luck and wishes - as for me - I find that all inclusiveness is a better business practice instead of exclusive... I am just glad that StartUpNation let me in and was not age or gender specific... I am also a volunteer with a NPO and we currently have a 15 year old designing websites for our organization - we are all inclusive and welcome participation from all age ranges...
today is the present and tomorrow a gift...
