I filled it out, but this isn't a random sample. It's probably going to be biased toward males aged 20-30 w/ lower-than-average activity levels, which are all factors that can impact the responses to the types of questions you ask.
If you posted this at different forums/websites/etc then that will help (though not so much if they are all gaming sites)
I'm a 31 year old firefighter who drinks 40+ ounces of coffee a day. I also play in mens lacrosse leagues and snowboard as my forum handle suggests. You'd be surprised who plays video games lol.
