There was an interesting article on MarketWatch about the increasing prevalence of websites offering prizes and cash for blogging, answering questions, searches, etc. The list they gave was pretty poorly done, but the article was interesting. So, I was wondering if you all know of or use these sites and have been able to make a little bit of money or win some decent prizes. I'm not looking to become a millionaire through this, but it would be nice to make a couple bucks here and there considering the amount of time I spend on the internet anyway.
