I love those 'the emperor has no clothes' moments. It is so refreshing when someone publicly writes something candidly about an issue. Something which everyone working in that field are thinking, but nobody has said out loud. Some because they are afraid of losing their aura of respectability by speaking too harshly, others because they are weary of the resulting besiege by those that can't see the facts straight.
But sometimes, if something is a load of crap, somebody may point that out.
