I'm not sold on this niche stuff, so what a guy likes midgets with red hair. But what if he likes giants with red hair too but didn't know it and there's overlap in his preferences? So does that mean he likes two niches now or does that mean he doest like any niche he just likes to fap?
And just because something has been done forever doesn't lessen the gag reflex.
Seriously can i goto the library and get a book on niches to help me run my business better?
