I haven't been following LessWrong for that long, but I gather that there was a time when Will Newsome's comments were a lot more.... orthodox. I'm guessing that fact has a lot to do with the way his criticisms are received now.

He can still be found on the SingInst about us page.

Another big reason I avoid talking about my disagreements is that they are sufficiently fundamental that I expect a large amount of pushback. I know I find it very hard to disengage from argument, and I suspect that's also true of a significant proportion of the posters here, so I'm worried that the discussion will be a horrible time suck. I really can't afford that right now. Perhaps at some time in the future, when I have a little more time, I'll write a discussion post detailing some of my objections.

You do your name justice.
