If no one wants to, then you have an empty thread, which is spam. If you want to talk about a specific subject, go ahead, but just making a thread just for the sake of it isn't okay. People can still discuss things, if they want to, by making a thread themselves, which takes out all the threads no one wants to talk about, a.k.a spam. If you feel the need to talk about something, ask a question about it or talk about it in the first post yourself a little, like what your favorite things about are, etc.
All I want in life is peace, love, understanding, and a chocolate bar bigger than my head.
