Usually serious topics don't attract many people, but saying stupid things will. Take a look at some of the drama topics with 30+ pages, especially the Nickpb drama. Comments don't really mean it's better, it's just how much attention it gets. Ambiguous topic names can attract more people than usual.
I mean, look at Obama making promises during the debate before he was president, and look at Annoying Orange's path to getting rid of illegals and building a giant wall on the border of Mexico.
