On your 'about' page as well as in the linked article, you criticize GiveWell for vote counting. The example you cite of this is their microfinance review. I don't know how solid this review was, but there are at least plausible reasons for treating the null results as negative evidence in this case, and I would bet on GiveWell's analysis over your meta-analysis but not confidently.

Do you stand by the claim that GiveWell's analysis is badly flawed and that donors should trust your meta-analysis of microfinance instead? If so, I'll look into the case more closely and update my views accordingly.
