Agreed, most of the topics on steemit are useless to me too. I don't give a damn fuck about people presenting themselves, steemit bimbos or dudes wearing bikinis or make up trying to make a buck.
I want to read topics that i'm interested in only, stuff that i really care about. Internet marketing, photography, hobbies to try, activities to try, stock market, nanotech, etc. And other people will be interested in other stuff. Good for them, but i don't want stuff that i don't care about to show on my screen.
