I can tell you that as a former Reddit user, Stacker News is far far far better than I imagined. I think territories can be moderated here, but users have the power to downzap a post or comment which they find is not suitable for the community. Territory owners are just a mention away if you think something is not going well.

Didn't see it.

The UI and the whole way this site works is slick and modern.

Could happen, but as I said, we all can downzap the shit out of them, mute them.

Do we have one? The only closest thing is @saloon, and we can see how well the concept works there.
