What catergry are your stories in? I mainly add to others in the erotic couples section when i write for other people. Also if ive seen people say they will add threads in return for yours i'm more inclined to add to theirs. Just my reasoning
those are mind. i normaly write in the fanfiction and sci-fi section. I pick those because those stories tend to have more plot and variety. I also like the mature section
I find people are attracted to choices it seem. So I try to make sure the story goes into differnt directions and fethishes (some that not even mind)
I also tend to add to those who add to mind. Also add to thier thread they added. The promblems your not told when someone added to a thread that you added in the story
Chyoo is a great site but really wish they would add more features
