From the blog of author (and one of the most insightful people in the world), David Brin:
CITOKATE: Criticism Is The Only Known Antidote to Error. Too bad it tastes so awful, to be on the receiving end… so that most of us never even thank our enemies for pointing out our mistakes for us. Think about that. If criticism is the only way we catch our delusional errors, why do we resent those out there who willingly, eagerly, give us what we need, in order to do better and to be better
It is a gift economy! After your foe has heaped upon you a laundry list of things to fix, you should thank him or her… and then return the favor! Purely (of course) out of the kindness of your heart.
