Why does nobody comment?

Ok so earlier today I posted a blog asking for redstone challenges saying specifically to leave a comment saying a challenge they wanted me to do. I received 1 comment asking for an elevator. I completed an elevator and posted it and again in the description I asked specifically for people to leave a comment stating a redstone challenge for me to do. This time nobody commented on it. Why does nobody leave comments when specifically asked to? If you are reading this and can think of a redstone challenge then PLEASE LEAVE A COMMENT and tell me what. Also if you have an idea as to why nobody would comment then PLEASE LEAVE A COMMENT explaining why. Im frustrated because I submitted the blog so that I could improve my redstone skils. So one last time I ask. Y U NO LEAVE ME COMMENT?!
