Now some articles earn more, so obviously, those are worth more. Many haven't earned me anything at all to date, although it's impossible to tell what indirect effect they have (for example, they could generate interest in other articles, or generate Amazon sales. In any case, on most sites, each article provides a backlink to your other online properties, and your profile page (or should, at least). So when your friends, family, or financial advisors laugh at you for spending hours at the computer, typing away, remember that this is a serious investment of your time, and will pay off in the future, perhaps even in unexpected ways. After all, we don't know what is around the corner, and those of us with established online properties, especially on young sites, stand to benefit.
