Do you have to narrow the focus of a niche?
I have a niche that I feel would be great, (home-renovation) and a great domain available to match it. However, there is a lot available about the topic already and I don't really see a way to effectively narrow down the topic without limiting myself too much. I am not interested in kitchens alone, or bathrooms or any other single aspect of remodeling. The whole big picture is much more interesting to me. Is it necessary to pick something with a much narrower focus?
