It's gratifying to know we come off as a friendly bunch in a snark-free zone. From my years of being here, I can attest that is not entirely by accident. I haven't seen it get so bad the moderators have had to step in, but I have seen trolls come in looking to start it up and quickly leave upon discovering folk here ain't having it. It is a pretty sophisticated crowd here when it comes to heckling or dissension. Again, I can attest, it is also a diplomatic membership. After being on the web a while, skilled users can usually spot the troll before finishing reading the first sentence.
