I want to do affiliate marketing, but I have no idea as to what niche I know enough about or have enough interest in to write about to come up with a whole website concept. For those that do affiliate marketing, what do you do when you just don't know what to write about next? I would like to hear stories as to how you got started in affiliate marketing and how you decided on your first niche. Also if your first niche was profitable or is still profitable. I want to hear some stories to give me a little more boost to get me started.
