Agreed feedback is tough. One of the problems is that it depends a lot on the setting and team. A person in one team might get some kind of feedback, but in another team the same person could get the opposite advice.

The other problem in our industry being relative inexperience of many people. When everyone in the team has had < 5yrs experience who is really qualified to objectively describe what a person is doing wrong? I know when I was a an inexperienced manager I gave "constructive feedback" that I now recognize was wrong.
