::::I included the GiveWell blog when I mentioned "links to blog posts".  I personally think that it all hinges on that one blog entry and that its reliability is subjective.  I'll let Kudpung speak for himself, though.  I've probably butted in too far as it is so the trout stays! I'm never opposed to a trouting anyway.  I think a little silliness is good for productivity.
