I continue to be impressed by Holden's thoughtfulness and rigor. If people want charity evaluators to start rating the effectiveness of x-risk-reducing organizations, then those organizations need to do a better job with (1) basic org effectiveness and transparency - publishing a strategic plan, whistleblower policy, and the stuff Charity Navigator expects - and with (2) making the case for the utility of x-risk reduction more clearly and thoroughly.
Luckily I am currently helping the Singularity Institute with both projects, and there are better reasons to do (1) and (2) than 'looking good to charity evaluators'. That is a side benefit, though.
