For a long time, my feeling was simply that open discussion should be held above all things. However, I also hold the philosophy that Hubski should enable self-correcting of bad behavior, based not upon top-down moderation, but upon the community's actions. For example, currently if you don't like a user, you don't follow them. If you don't want to see their posts at all, you ignore them. This allows users to see the kinds of posts that they want to see. I am sure that some users will be over-zealous with banning comments, and some won't. It's possible that over time people will simply choose not to follow over-zealous moderators. However, there may need to be some mechanism to keep people honest, such as making the list of users they ban available.
