This seems fairly exploitable.
I post a question, and wait for answers. I create another account and answer it. I pick my own answer as the best answer, and I lose no money. I gain the information that others gave me for free.

Google's the worlds leading expert in click-fraud, I'm sure they can figure out if you're doing this.
From their FAQ: "Do I have to pick the winner of my contest? If your contest receives less than 5 entries by the time it ends, you're not obligated to pick a winner. You have the option to extend the contest for seven (7) days for free. 'Extend Contest' and 'Contact us' link information is available on the contest page.
So, what if I just forget to log back in and award people the prize? Does google automatically pick a winner?
How does Voting work? You may vote on as many contests as you wish. However, you can only vote for one entry in a given contest each day, and you may not vote for yourself. You do have the option to vote for more entries in the same contest tomorrow! If buyers don't pick a winner when the contest ends, winners will be chosen by popular vote.
All the time.
It will be like yahoo answers with money. train wreak waiting to happen.
I assure you the best answers I gave/got at stack overflow and some other content specific forum was not because I/they needed $5 to help somebody else.
