I discovered Hubski about 1-2 weeks ago, and really enjoy it so far (even though I am a little quiet). It reminds me of when I first signed on to the Internet in 1994, how the communities were small, but close and respectful in dialogue. Much more signal than noise. I wish the founders nothing but success -- but I also hope Hubski doesn't grow so much that it loses its culture. (Perhaps keeping the culture in the long-term /is/ the measure of success!)
that requires barriers to entry, either through obscurity or a vetting process. Otherwise eternal september happens.
You are the barrier to entry. Who and what you follow is what builds your feed. If you consistently see unsavory users in your feed you can "ignore" and or "mute" them. You can do the same with URL's and tags. In short, if your feed sucks, take stock of why and change it. erin is right, whether or not we can maintain this overall culture is the measure of success though, from where I sit. But, should the idiots intrude conceivably you may not even notice.
