I have definitely been frustrated with handling of my specific niches. I think it maybe has to do with when you add a site to your system vs. when you add a niche tag. Not sure, but like
SpookyCash has somewhere between 0 and 1 listing in tags like tattoo, rock, goth, extreme hair, etc. when SpookyCash has a lot of sites perfect for that traffic. And, if I don't know the difference between punk (FETISH) and punk (WIDE FETISH), I'm guessing most webmasters would be baffled by the distinction. It might make more sense, from both a usability perspective and an admin one, to have fewer tags but with very complete listings in each. Another suggestion I would make is to have the listings in longer categories rotate or be listable in more ways than just most recent, as the current format often means the best and biggest sites in many niches are at the end because they are the ones you thought of first, when entering data.
