I was surprised that there were some out there who dislike an increasingly niche culture. Then it struck me in one sentence. It is harder to market to niches. Although if you do there is a great benefit in that you can profit off of the long tail. For example if you make custom travel humidors with extra options like a watch winder on the bottom. That is a really, really specialized item, you are looking for someone who smokes cigars and has an automatic watch that is into traveling. Where but skymall could we such randomness? The answer is in niche forums, places where people with very specific interests can go and nerd out together to there hearts content without boring the ever-loving pants off the rest of the population.
I for one am a nicher through and through. I think that the mass individualism afforded by the internet and modern technology are a wonderful thing.
