I agree that this would be a good idea, and agree with the points below. Some discussion of this took place in this thread last Christmas: http://lesswrong.com/r/discussion/lw/je9/donating_to_miri_vs_fhi_vs_cea_vs_cfar/

On that thread I provided information about FHI's room for more funding (accurate as of start of 2014) plus the rationale for FHI's other, less Xrisk/Future of Humanity-specific projects (externally funded). I'd be happy to do the same at the end of this year, but instead representing CSER's financial situation and room for more funding.
