I was going to ask what prompted another wave of interest from Reddit but this seems to summarise it. In short: arseholes again. Not 'arseholes on that site'' or even, perhaps, 'arseholes enabled by anonymity' but just a fundamental, fist-clenching, existential 'why are there so many arseholes in the world?' problem. We've had some rather excellent discussions here about the enabling of appalling behaviour by the conjunction of arseholes, opinions and anonymity; also many about their simple, baffling existence. What I like about Hubski's userbase is the approach to these discussions is one of genuine investigation and on the whole it's not flame wars we get here but a conflagration of thoughtful discourse.
I'm looking forward to getting into such discussions. I see that it takes a while to form a new habit (such as going here instead of reddit first thing), but I have no problem making the effort for a saner community.
