This will be the result of this thread; I know it. I knew from the start, but I was curious. As others before me already discussed, it's something that stuck with the site, starting as a meme and being taken seriously by newcomers. I will be a dickhead about it, and if I see complainers, I'm gonna spam my thread about it. Suck it!
Now, for real. Looking at the numbers, I think it's a healthy balance. There is nothing wrong with it. People... Listen... You feel you can only do well with smut and harem on this site because, let's face it: You didn't write something people enjoy. Success doesn't come in a day, nor does it fall into the lap of every harem and smut story.
If you are jealous of the above-mentioned genres being in the top 10, top 5, or top 3... go and write something that people like and don't have those tags. It can be done; It has been done multiple times. Instead of crying, get yourself together and get to writing.
