I've been thinking on these issues recently, and plan to eventually create a post to discuss it.

For one, I believe that we can lower the entry barrier a bit once again, enabling new users to post more readily, and yet keep our anti-spam effective and low-effort.

Here, we take the approach of putting as much moderation as possible in user's hands. I consider how we as people moderate our interactions in meatspace, and take a lot of cues from that.

IMHO there are social dynamics that arise from top down moderation that can be positive in the short run, but often decay in the long run. I believe that the summation of individual choices results in the best of spaces, because participants do not have clear leaders which give them cause to champion opinions or to form factions that result from such opinions. I do not believe that there is such a thing as a proper space, or a safe space, or even a thoughtful space. However, I do believe that people can feel that spaces are proper, safe and/or thoughtful, and that they can choose to frequent them for those reasons.

I believe the fact that physical architecture outlasts social architecture says much about the human condition.

All this said, I do think that Hubski could sustain more thoughtful interaction than it does, and that it could be a better example or counter-example for online interaction in general. It's a goal I'd like to meet.
