I mean this in the most constructive manner I can muster: consider that you contribute to this in some way. To put it more bluntly, maybe it's you. Because I've lived here for seventeen years, having moved from the Midwest, which was a hell of an adjustment. Because I'll agree that Seattlites are generally not as outgoing. For example, you move into a neighborhood in the Midwest and you'll be eating casserole for a week as the neighbors one by one drop them off. In Seattle, meh, it'd be nice if the neighbors acknowledged that I'm new to the neighborhood. But to just not talk to you? Really? An entire geographical location comprised of people that won't talk to others? C'mon, how likely is that? Hell, most people around here these days aren't even from Washington, so they're just fast learners of local culture?

Now I'm a bit of an introvert, so I'm not all that outgoing to begin with, but I have no trouble getting people to talk to me. Not as "chew your ear off" as Midwesterners can be, but they'll talk. If I had anything to complain about with West Coast living in general is folks can be a bit self-absorbed compared to what I'm used to. So they'll talk; oh, how they'll talk, but it'll be about themselves. But at least they're talking to you. :-) So ask people how that Paleo diet is going, or how Crossfit workouts are treating them. My experience says that you'll beg them to shut up.

But all of this is one huge, monstrous generalization because you can't just dump 700K people into one pigeon hole and call it a day.
