You are, however, consciously choosing people from different walks of life. Organically, people do striate by interest.
I like passionate people. One of my favorite people to talk with is my uncle Bill. He's a DIE HARD libertarian and has been since John Stossil was a much younger man. Still, he's a really smart guy and I learn a ton when we talk. He's passionate about his beliefs and as such he's way more fun to talk to than someone I might be lock step in belief with that is less passionate. I like to surround myself with people that are doing things. My wife is the same way. I feel like Hubski has cultivated a similar group of people that I would actually hang out with in real life. I've disagreed with you, with cgod, with many people on this site a lot, but I know that if we were all in a room together, having a beer, it would be a blast. Dissenting opinion is the bedrock for growth, I'd welcome 10 people with differing views from my own to Hubski gladly, in a heart beat. I'm not sure why anyone wouldn't? You, no doubt, have friends that have varying views etc. too.
Because statistically they don't. People are most comfortable amongst those with similar beliefs. This is why political parties and religions exist. Mad props for pushing for diversity - and you aren't the only one. However, it is not the natural behavior of groups and if you aren't cognizant of the statistical mean you're going to be disappointed in the results.I'd welcome 10 people with differing views from my own to Hubski gladly, in a heart beat.
