Another part of not replying in the comments (or anywhere publicly) is that I want to be able to speak to individuals how they want to be spoken to, without fear of alienating others in the process. I can be very friendly or very mean in email exchanges with people--from sycophantic to menacing. I don't want side effects of those conversations spilling over into other interactions because it will limit my future ability to convincingly be whatever I want in any particular situation.
Finally, I don't reply in the comments because I feel like it chills discussion. If I was active in my own comments section, fewer people would comment. They would be waiting for someone else (me) to say their thoughts for them. Some might be afraid to say something and have me contradict them or disagree. If I have something to say, I say it in a post. Otherwise I don't want anybody waiting around to hear my opinion on something. As it is, other sociopaths are ruthless with the people who (they think) put too much stock in things I say. It would be much worse if I interfered with the comments section as well. I don't want issues I discuss on the blog to always degrade into a war of personalities. Plus, I have found that silence is one of the best ways to elicit information. And I think part of the reason the blog is appealing is the diversity of very freely expressed opinion.
I selectively disclose information about myself for strategic reasons. For instance, I never talk about my gender or even strictly about my ethnicity or other demarcating personal characteristics. I hope by doing so that I will be a blank slate and people will be able to project their own ideas onto me. I want to be like Kim Jong-Il or Obama, a figurehead, a receptacle for people's hopes, dreams, fears. I want people to directly relate to the blog--to think of the sociopaths they love in their lives or the sociopaths they hate. If I got too specific about anything, the illusion would be broken. Instead I stick to generalities (like Kim Jong-Il and Obama) and let people fill in the blanks in whatever manner they feel inclined. When people write to me and say that I seem to describe perfectly their own experiences, either as a sociopath or as someone who has known a sociopath, I know I have been successful.
I am pretty good at choosing a particular featured photo for each post to set the mood. Sometimes they have an underlying meaning or reference to the blog post, sometimes they're random but I use them anyway to give the illusion of something deep but unstated.
I know people like to criticize or rally so sometimes I publish something for the sole purpose of galvanizing readers or provoking discussion/fights/ridicule. It keeps people blood thirsty and/or engaged.
As anyone noticed anything else?
