I'm not sure that it is true that there is even such thing as decorum on social media, or if there was, if you could reasonably define it. The Internet is a global communications system linking hundreds of countries, thousands of cultures, and perhaps millions of sub-cultures, class affiliations, and tribes. Even the fact that we are here, on HN, speaking English puts us squarely in the minority of people who use the Internet.
