Well, it depends on what site you are talking about and what you like to work on. In the online world you can have many income opportunities, but you have to see what you like and what you want to do. For example, I work on 2-3 forums, I have 2 applications on the phone with surveys where I am eligible for each survey + 2 games where I am paid to play (in paypal). In total, per month, I make somewhere at 200E in the online world. It's ok for me, I'm satisfied .. I spend somewhere at 3 hours a day on the PC.
