Have you heard of Jingit.com? It's a great site, and you can earn up to $40 a month simply by watching commercials and answering a few questions about them. Now, you do actually have to WATCH the videos, as jingit will pause what's playing if you navigate away from the page. However, nothing is more than 2-3 minutes long, and on average you only spend about 10 minutes a day there. Jingit.com also has a smartphone app, where you can earn even more by watching videos, and even "checking in" at places (similar to foursquare). I recommend joining now, while the community isn't HUGE, as I'd only assume they will eventually make sign ups more limited.
