Well, to be honest I have heard this phrase some times already, like don't use the forum to make money. But just explain me, what all those people who work for signature and bounty campaigns are doing here? Don't they make money from the forum? They do! I am ready to bet the biggest part of users are exactly for this target here, maybe you too  
I came here to learn and I have learned something already. The forum can't bring me that good profit that I am looking for, it is possible only with high ranks, to reach it I need to become an active commentator and spend here over a year and it's everyday work. I have found for myself that trading suits to me the most on my current stage and I am planning to concentrate on this. And I will "use" the forum only for getting the info that I need to atcheve that
