Hubski has a better mechanic than reddit: because it's sharers and followers I find it makes me think more about whether other people really need to see what I'm about to share or whether I'm wasting their time. And it's great to be able to remove someone from my feeds without censoring them for others. Then again, I felt similarly about reddit when I first used it back in 2008 or so. Reddit seemed like such a sensible site where people with expertise discussed serious topics, compared to the fluff on Digg. You would think twice before posting on reddit. Things change, and it's still an open question whether Hubski's more civilized culture would survive a huge influx of users. Especially if that growth put it on the radar of the various propaganda "influence" campaigns. But one thing Hubski certainly has going for it is the lack of corporate pressure for growth at all costs. This guy hits that nail right on the head.
