Who are the social media innovators in Seattle and Vancouver?

Regular readers of Pro PR will have noticed that I’ve been posting video interviews with people who are leading the way in developing social media applications or applying social media in innovative ways for community building, marketing or organizational communications (either internal or external.)

I’m going to be in Seattle in mid-August to attend Gnomedex. I’ll be spending a day in Vancouver on my way there.

What Seattle or Vancouver-based social media companies and executives would you suggest I try to interview while I’m on the West Coast?
