I disagree entirely, and think there is some sort of "lets pretend we are talking about what we say we are talking about" bias at work here.
Will SAYS he is talking about reducing his credibility. He then does not use a host of tools which would do that very effectively ( I think there are many choices, but making errors of fact and logic would be a good start). Speaking cryptically is NOT a very good way to reduce your credibility, except possibly among some subset of people.
What Will is more successfully doing is 1) intriguing a subset of people 2) tweaking the crap out of a large subset of people (in a way that seems orthogonal to credibility seems to me)
Just because he SAYS he is trying to reduce his credibility does not mean that is what he is actually trying to do. I am not sure what he IS trying to do.
Thank you for your cooperation and understanding. Don't worry, there won't be future posts like this, so you don't have to delete my LessWrong account, and anyway I could make another, and another.
But since you've dared to read this far:
Credibility. Should you maximize it, or minimize it? Have I made an error?
Discuss.
Don't be shallow, don't just consider the obvious points. Consider that I've thought about this for many, many hours, and that you don't have any privileged information. Whence our disagreement, if one exists?
