Reddit has become user-centric in many ways. This is one of the largest problems with reddit, but it is fact. hubski is most like tumblr mixed with twitter, I suppose. It doesn't strike me as remotely similar to facebook.

And Facebook, Tumblr and Blogger all give the provider of content the option to censor other users on the content they post.

You mean in the sense that if I post something I can limit who 'shares' it to just my close friends or whatever? Okay.

I'll conditionally agree with you. If indeed there is a problem with the personal side of hubski, which I haven't myself seen evidence of yet but may in the future, then I admit that some sort of solution might be needed. However, it may just be that hubski will remain a personable version of tumblr/reddit, and if that's not your niche, it's not your niche. Curbing this hostility could accidentally curb what many of us like so much about hubski, and I can see why mk would fear that.

Good discussion, sorry for my weather balloon-related dig at the beginning.
