What do YOU want out of a feedback system?

So people are complaining about feedback. We know it's not perfect, so no long diatribes about how and why it sucks. Rather tell us what you want out of it. More specifically, what are the most important things you want out of a feedback system?
Be concise. Get to the point. Bullet points, short sentences. When I start to read long speeches that take up the whole page, my eyes gloss over and I skim. Oh and save the "tank it all" posts.
Thanks.
What's been suggested so far:
What you want to know
Gameplay (overall quality, strategy, teamwork, make/break agreements, suicide, create chaotic game)
How often they miss turns and/or deadbeat
In-game behavior (conversation, attitude, made game fun, abusive)
Suspected cheater
How you want to know it
Ranking/Rating system
Individual scores for specific criteria
Comments on specific criteria
YES or NO option on 'would you play them again'
Check list of specific criteria
Tell at a glance I don't want to play this person
How you want to be able to leave it
Ease of use (no long forms)
Free speech, Ability to leave jokes
Write the way we talk in real life
Don't allow stupid feedback
Focus feedback for critiques of players who deserve exceptional praise or shame.
Time delay on making feedback viewable
How you want to dispute it
Clear, published guidelines that are the same for every player
Fast response
Analyse both negs and the game and see what applies what doesn’t
