Well how do you have a discussion about something so wishy washy as superstition without it turning into a chat thread? You can't exactly debate superstition (unless you are debating the merits of superstition itself). And since this forum doesn't support chat threads (something that I completely agree with) that could be why they lock this stuff up. Just my guess.
That or talking about superstition is a superstition of one of the moderators. Probably Photon, he is very much into "new age" stuff like that.
