I think that the discussion here is somewhat misguided. ....
Even if XMRV turned out to not be the answer in terms of research, the CAA would've done a terrible job if they don't make XMRV the answer in terms of funding. Interest has never been higher. The job of patient advocates is to translate that interest into research dollars.
I agree with a lot of what you say, but you can't really expect the CAA to raise money based on the XMRV discovery after they've cast doubt on the study?
Also, I trust you know that the CAA has only very recently gotten into the business of directly funding research at all.
I would love to see the CAA accomplish just what you say, but for the moment donors have every reason to think that their money is more likely to go to xmrv research by donating directly to the WPI. (If they give to the CAA, the money might go to advocacy stuff like the "Faces" display.)
