I had problems reading all of this because the tin foil hat I'm wearing kept slipping down over my eyes.
Seriously, guys, simply because you can describe something does not mean it exists. There are a LOT of ungrounded premises here. As an example, simply because somebody begins an argument with a weak premise doesn't mean that there's an organized effort at "consensus cracking". Sometimes people just make weak arguments.
There is a danger here, and it's the same exact danger as folks face that get caught up in lists of logical fallacies. The danger is that they believe that human conversations should follow a strict set of almost mathematical rules towards a logical and inescapable conclusion.
Got news for you: people are not robots. Conversations among people are messy, emotional, many times fruitless, and non-linear. Most every topic involves incomplete information, and the soul of rhetoric is emotive persuasion. The purpose of learning things like fallacies is to prevent them from being used in a careless, overt manner such as to shut down communication. It has nothing to do with eliminating them from speech or somehow perfecting the discussion. Intelligent people just make more subtle and persuasive fallacies, which makes sense when you realize decisions must be made on incomplete data. In the same manner effects such as these should be seen on all sorts of forums -- whether or not somebody is employing a tactic or not. The author is looking at this backwards.
That doesn't mean that such techniques aren't being used or wouldn't work -- although I have my doubts that you could constantly "own" a board through using them. Seems to me you'd just end up being cast as a manipulative asshole.
This article was just a little too much on the paranoid side for me. I'm not sure it belongs on HN, or that it contains any useful information at all. The problem is that these "principles" are presented more or less as simple supposition. It would be like reading a list of "wonderful" ideas for a startup. The only value some article like this would have is if it were somehow presented with empirical data of value provided. Of course, how you could actually produce value in taking a conversation off the rails is beyond me -- how do you know that by using one of these techniques you're not actually assisting somebody in understanding a topic or gaining value from the forum? From what do you measure?
It's just speculative unsubstantiated paranoid bullshit held together by an intelligent mind and cogent essay. I'm not flagging it because in some sense I guess you could call it hacker art. Very Hari Seldon.
