To the dude above: Olympia is the capital, durr...
Seattle is a pretty sprawling city, and so there are dozens and dozens of different neighborhoods, each of which have a remarkably distinct flavor and feel.
If you want a good-old fashioned neighborhood, try Maple Leaf... want a cosmopolitan singles community? Capital Hill or Belltown. Bohemian? Fremont. Tons of areas to choose from.
The traffic here is not bad, at all. People will complain and cry about it being horrible; I can get from North Seattle to Downtown in fifteen minutes during rush hour. When I lived in LA, getting from Mid-Wilshire to Downtown or the West Side took at least an hour and fifteen minutes. The busses here are great.
It's not the rain - there are rainier cities than Seattle - it's more the grey. You have to cope with almost uniformly-grey skies from October to April, and at the peak of the winter, it gets light around 9-10am, and dark around 2/3pm. The flipside, of course, is that in the peak of the summer, it gets light at about 4am, and doesn't get dark until almost 10pm.
