Regarding off topic: Yes, exactly Sakura. These are specific topics of conversation posted for answers regarding that topic. If all of us would just take a second and think, am I contributing to the OP's topic or question? And if someone isn't, we can ask them to start a new thread in a recommended section.
I've been just as guilty of it and probably never gave it a second thought before I became a mod. And honestly we are not that stringent about this. You guys have gone off topic and it's been left largely alone. Mostly we address what is reported on. But, it would help us if the users did a little self policing.
I'm thinking this is a good step in that direction.
Edit, the Face behind the Name thread is a great example of some off topic-ness that has been left untouched. But if you've ever tried to sift through that thread to see just pictures of people? It would take all day. :P
