We will discuss this on our weekly Monday call. Anyone reading this, by all means put forth ideas, tweaks to current functions etc and it will be considered. For the meantime, I'd suggest using what kleinbl00 referred to as the 'ol triple block -remember that enough of these will keep their posts out of the global feed. Comments on the other hand... -we need to work on this. Thanks in advance for any ideas/discussion.
In regards to potential moderation, I just want to point out the risk of moderators' abuse of power--in the distant future anyway, I imagine whoever is chosen to mod atm is an absolutely trustable person involved in the inner workings of the site.. but you're going to always need more and more mods if you choose that path, and things can go sour quick.
We have no intention of choosing that path. There has to be other options....
Then this right here is where Hubski innovates. We've got some wicked minds here, put em together something will work.
