Criticism is welcome, but remember to give constructive criticism, which includes consideration of how your criticism will affect the other person emotionally. The golden rule applies: how would you feel if you read the message was directed at you? It's hard for someone to constructively make use of criticism if receiving it is an emotional drain.

@cwebber Funny thing is I find most Americans and Brits are so concerned with not hurting feelings that their criticisms are sugar coated to the point of being effectively useless even honest.

If I were to follow the golden rule I'd be harsh, to the point most people would see it as almost mean. Because thats how I want people to be with me, brutally honest.

The golden rule only tends to work when everyone has the same sensitivities as you.
