... there have been Trolls underneath
I don't know what it is about JU -- probably because, even in "Internet time", it's a pretty young community. But this place just loves to feed the Trolls [q.v. Link].
I don't mean just offer them sustenance -- the users seem to actively go out of their way to find posts that are offensive/ridiculous to them and actually help promote these articles by participating in flame wars.
I doubt everybody here is that much of a n00b -- everyone probably knows about the Scoring System (Link).
We've all been flamed -- especially in some of the more heated political debates here. But just ignore the obvious trolls -- including their posts/replies and their articles. No moderation system can really control them but giving them your valuable time and attention rewards them with what they want the most.
