I am going to question in advance any possible validity to your poll results. First, any poll that requires you to login to yet another service (like Google Friend Connect) will limit and bias your sample. (I’m not going to join something just to answer a survey, and I know plenty of others who feel the same way.) There are many free and public survey tools (e.g., surveymonkey) that do not require this. Second, asking only first choice on a limited set throws away information and yields spurious results. First and second choices or, better yet, ranking, yields more information and more meaningful results.
