If you state your opinion in a virtual "room" with 300 million other people, the chance that at least 1 of those people vehemently disagrees with your opinion is a certainty.
Conflict is almost unavoidable on mass "social networks". Some people claim that you shouldn't live in an online "bubble", but I, uh, vehemently disagree. The only way to keep your sanity online is to live in a bubble, just as you do in real life, self-selecting which people to congregate with in rooms.
You may ask, having said that, why am I here in the HN comments? That's a good question, and the answer is obviously that I'm insane.
Does anyone find it weird that the author of the article claims that we actually need online arguments to "hone our thinking" or some such nonsense, but then immediately goes into an extended analogy about hostage negotiations? I don't know why we all need to become online hostage negotiators. If you want to learn something useful from a different perspective, go offline and read a good book.
The author says, "Taking a disagreement offline can work, but it should only ever be seen as a second-best option." Why???? Everything else the author said suggests it's actually the best option. I really don't see the point in online arguments. Do they ever get resolved? Not in my experience. In fact I fully expect the same (non-)outcome in any replies to my comment.
