Excellent, I will check all of these out.

One of the methodological issues facing me as I worked on this was whether or not to include people who were not x-risk researchers but who had written a piece or two about x-risk. Several of the authors in the new Global Catastrophic Risk (2008) book appear to fall into this category. In practical terms, the physicists who are x-risk researchers have the same resumes as physicists who are not, but making the distinction does keep the list from getting too long.

I say all that because I may or may not decide to include each of these people in the roll call. Your effort is appreciated regardless.
