Seems like setpixel now wants more than just your email:
"Since long before the web, the anonymity of online conversation has lured people into being much ruder than they'd be in person. So the principle here is: don't say anything you wouldn't say face to face. This doesn't mean you can't disagree. But disagree without calling names. If you're right, your argument will be more convincing without them."
