Ahhh - but news aggregators are not user-centric. Hubski is more like Facebook or Tumblr. And Facebook, Tumblr and Blogger all give the provider of content the option to censor other users on the content they post. Hubski does not. In many ways, Hubski is a hybrid between Reddit and Tumblr. If you want the Tumblr touch, you need to Tumblr control. I'm advocating a good deal more discussion and investigation on how to continue incentivizing providers past the point where they attract controversy lest they decide it isn't worth putting up with the bullshit (done this twice now). That incentive could easily be "come up with ways to foster community such that a culture of hostility is curbed before it develops" but my discussions with mk so far have been along the lines of "I'm don't see any way to deal with this that doesn't stink of censorship so I'm not going to work on it at all."
