BrandPort is wooing 18-to-24-year-old demographic by money: the company pays $0.25 to $0.50 per ad to college students who are willing to watch the commercials online. Payments will be made via PayPay in $5 increments. The service is only open to people with .edu email addresses.
I am skeptical of the results. As Paul D correctly pointed out in a blog comment at Business Pundit, paying $30/hour is not going to be a sustainable model. I also believe some smart students can create multiple acceptable email addresses to game the system and make a living out of the site.
