it depends on what you mean by stuff...
have i done well by using the site... yes, but not in the way you might think.
i make enough from adsense to pay for my hosting accounts. but adsense is the gravy, not the reason for writing hubs.
if you think of this as an article directory and write good content, you can generate traffic to one of your own websites. now, i'm not sure what type of internet business you are thinking of or working toward, so i can't offer you a strategy that will fit your circumstances or goals.
bottom line, if you use this place the right way and for the right reasons it can pay off for you.
