As an online environment I think we would do well to write a list of principles to point people to. Similar to the 10 principles of Burning Man perhaps. Here are some ideas, what would you add?

Verify the note (your own too)
Don't trust the note
Practice v4v
Participate (help build)
Be constructive (use your own skills)
Zap the other 
Have a mindset
Accept bad notes as a a trade off
