yes you can say its like a business, but you cannot really make big money here unless you are a good writer that can write articles once every hour like the ones who invited me here. but it also depends on your skills and how you are going to make money here. i'm just working on my hubs in my extra time and its fun to answer questions and post on forums or read other peoples hubs, (actually, its really fun here)
there are many ways on how to make money with hubpages, see how. just click on the "my account button" on the upper right and click on the "affiliate settings" button, it shouldn't be hard to find. . your new here right?
