If the job is very simple like posting on forums, or something I enjoy doing for free like testing un-released video games, reviewing new movies, making websites for myself or friends, or posting or modding on forums I would work for a penny, a dollar or for free if I had time since I would be entertained for free while getting paid a small amount.
There are many people who join http://www.neobux.com/ and https://www.mturk.com/ which do simple tasks like visit websites by clicking on links or categorizing products which work for pennys to dollars per tasks, so if you are a fast link clicker, or typist you can make a few dollars an hour.
Also, there are some people who posts thousands or more posts on their forum, blog, or website which only make a few cents to dollars each from advertising, selling stuff, or referrals which can add up to hundreds to thousands of dollars a month because each article only make a few cents to a dollar, but they have thousands of articles. when multiplied by 0.50-1 dollar each in earnings, they can make a lot based on quantity.
If GF has a lot of Traffic, and GF have a referral link on the forum or blog for your NeoBux account, and a lot of people uses your NeoBux referral link to join NeoBux. You can earn extra money from your referrals activities. I know of some people from ForumPromotions.net who earn a few dollars or more from NeoBux.
The reviews on NeoBux is mostly good at http://www.imreportcard.com/other/neobux
It's no doubt that mturk is a very great and reliable site to earn a good income online, but I would be better if I could withdraw the money to my paypal account from my country instead of converting them to gift certificate.
Cool, I try it out when I got the time since Mxproject might benefit from having better prizes for contests once I can earn more money to buy prizes for Mxproject.
No way.
Our time is way more precious than a few pennies and dollars. That's what I believe and I barely get any free time for myself. So, no way....just no way.
