[brainstorming] How to pick your subniche and develop them to a semi authority site

Still Mini sites works well if you do it well , need to be a bit creative and provide some value to the readers. Just creating website for adsense or any affiliate won't work , but if you can add value to a mini site , it still works great and you can convert these mini sites to a semi authority by clubbing the sub niches together and develop your idea. I have many success stories reported by following this strategy.

Now the important problem with this is , where to start. Ground rule is , start with what you are interested in or knowledgeable at.

Following are the list of niches you need to stay away from and others are the ones you need to think about. Following list might give you an idea how to pick your sub-niche.
