Yeah the nsfw tag - no profit in it really. If I were you I'd just take "risky" shots like vermillionfox or artedellavita. Just verging on the nsfw tag but not quite there yet, ya know? Start taking photosets instead of one or two shots in the posts. Let people get to know you and your thoughts more. Maybe do a contest or two to gain viewership. Get creative until something takes off. I know thaiprincess wasn't doing so hot at one point but now she is seeing steady dough flow with a variety of nsfw and life blog type posts.
