I have just read the book Start small, stay small by Rob Walling. In this book, he suggested a couple of method of find a niche market to develop products for. From that, I am currently researching for a niche market to start in, and wondering what an ideal market size might be.
I think that if the market size is too big, certain problems will start creeping in. Problems such as support, maintenance, on-going product development. On the other hand, uncontrolled growth can also be a bad thing.
For those who have gone down this path, what is your recommendation?
In your recommendation, can you give an indication on how your market size is measured? ie potential customers, traffic volume etc.
