I love internet forums, such a wealth of information! However, folks have a tendency to go over the top with some debates, and reminded me of this web comic. I have a forum I frequent for every interest I have and see these types of arguments on every one. What discussions have you seen in this forum that made you take a step back and say "woah"? Did you get deep into one of them and suddenly realize you were a bit too deep in the rabbit hole? One of the ones I've seen here is the great shaven vs. unshaven debate.
