Whether online, on the phone, by telegraph, or in person, we are governed by the same basic principles. The medium may change, but people do not. The question instead is whether the outliers, the trolls and the flamers, will hold outsized influence - and the answer seems to be that, even protected by the shade of anonymity, a dog will often make himself known with a stray, accidental bark. Then, hopefully, he will be treated accordingly.
