One of my favorite bloggers because of her ability to spot a niche is Suzanne ProChaska.com and fill the demand the niche has.
Suzanne managed to build a whole range of niche sites catering to women’s interest in skin care, makeup, clothes, and much more. And she’s done well catering to all sorts of products, including foundations, mineral makeup, … oddly enough, she got tired of zits and found that mineral makeup really made zit cream a thing of the past!
I’m still not exactly sure what Mineral Makeup is, but reading the introduction did help. I just wonder when she’s going to come up with a product that caters to men who suffer like she did from acne, even in their 30’s and 40’s.
