I personally don't read it because it's one humongous thread. If it was just like a Topic Area and had a bunch of Tobi threads in it, I would actually read it. I guess some people read it but in my opinion it's just a big mess.
I personally enjoy hearing other peoples theories about who Tobi is. They have become alot more prevalent and start to annoy people, but what the heck. I thoroughly read and give theories a chance. Go for it.
