In any case, I was trying to focus on the principle behind the story, not the actual story. The principle is that many physicians are looking for supplemental income because their day job isn't enough. They may find non-clinical jobs in the world of medical writing, sales, consulting, teaching, etc. Some are obviously more successful than others, but it's always interesting to meet physicians who have an entrepreneurial spirit. You can leverage common resources like eBay to build a business if you're creative and if you have the right business sense.
As for Dr. Jennifer Lickteig, I know nothing about her eBay activity beyond what's described in the CNN story. I've never purchased anything from her. I don't even know her eBay userID.
