Yes, but only in a limited way. It is more as an avocation that also brings in some side money, not a primary source of revenue.
When I say avocation, I really mean amateur activity in the deep sense - I do it because I love (amato) to write. Being able to express myself on any topic I wish is very important to me. So I would do it anyway. Doing it here at HubPages is ideal because it gives me audience interaction and some money.
In an ideal world, we would all earn a good living living our soul's purpose and being the gift we are to the world.
In this world, sometimes, we have to work for a living. We need a vocation, as well as an avocation. So I earn elsewhere, as well.
But I'll take back what I said: That would not be an ideal world. It would be an easy world. This is the ideal world, because the challenges make us stronger.
