editing version 2 (latest)
When you are editing the page or doing any action which relates to other people's work or opinion, try to explain why you felt there was a need to take that action as clearly and honestly as possible. Because, we have our own prejudices, presumptions, regarding certain things and we might simply be reacting to those beliefs - emotionally or intellectually. So, explaining the why helps us bring those presumptions to the surface and helps in clear communication with others. By explaining the why, it helps others to understand where you are coming from and it naturally brings a bit of sanity to the situation. Example : Instead of saying something like "That doesn't work", try to explain why it doesn't work and what all you tried and other details relevant to the discussion.
