Facebook group?

So I recently left an anime FB group that I was an admin for. Now I want to start a new group. I was thinking of something called 'Fandom Central'. I want it to be open to all fandoms, not just anime. Dr. Who, Marvel, and other fandoms would be welcome there as well. Im still thinking of things to do with it (like its primary function, really). What I've come up with so far is that while people can talk about the fandoms they like, others can post stuff that's for sale that relates to a certain fandom. Does that sound like something you guys would join?
