What drove me to Hubski was precisely the same reason although I suppose I got alienated a lot earlier. I've been on Reddit since 2009 when I was a wee lad and I remember things weren't really the same after the Digg migration. I don't even remember how I found this site but I've been coming back ever since.
The quality discussions and deep articles are awesome but I love the sense of real empathy here. I know Reddit's tagline is "come for the cats, stay for the empathy" but I find Hubski has a lot more to offer in that regard. People really pay attention when they comment here, it's not just yelling into the wind.
