Wave Interaction Protocol??

Wave needs an interaction protocol? Remember how forums post certain rules on how members should interact? I think Wave might need the same thing..I thought of it when I went into the first entry of a wave by my business associate and friend Clay Cotton. I edited his wave and made it better but he got angry that I edited his thoughts "the way he thinks" Perhaps Wave should be set so you can't change someone else's entry- or does that lessen the collaboration environment? What do you think?
