Firstly they ask me to create a Google account, then they ask me to register, including giving all sort of details such as my address and gender, and I get partway through the process and just can't be bothered. I've proved I'm a human, why do they need all this other information?

If I don't win, they don't need to contact me. If I do win, I can prove who I am. Don't make me go through all this crap up front just to what it's all about. I can't bring myself to care.

It's been said over and over before - the same thing goes for your web site. If you want people to visit, don't create barriers. If you want them to participate, don't create barriers. If you want a dialog, make it clear why it's worth participating.

Interesting to see Google think it doesn't apply to them.
