Even if I were making enough from HubPages to live on, I would still never plan to retire on this as my only source of income. We've seen in the past how search engines can change their rankings algorithms and kill your traffic. Even the most evergreen topic could also be done better by someone else, or HubPages could be superseded by a newer article site. At the very least, I would have to maintain and update my articles. If I'm still writing in order to maintain my retirement, I'm not retired.
