Joe, very cool that you are managing Linked:Seattle. I suspect you will make the best of it. Love the discussion you started about the possibility of dialoguing with Inslee about the economy, and asking for feedback.
I think I am a member but long ago changed my email settings so I have to GO to the group to see the discussions, which I haven't in a long time!
I guess what I loved about Biznik is that it was mostly self-employed folks. There's so much discussion on LinkedIn that is focused on getting jobs (you low-balled your estimate that perhaps 2,800 group members were looking for an "opportunity," as I'd bet money that a much higher percentage are on LinkedIn to network for opportunities... at least, that's been my experience with LinkedIn. It's not JUST an online place to post a "resume", but it is one of the best places to do that!)
So Linked:Seattle seems to be a very broad group. I think the question to ask is what common needs/ wants do Biznik members have with the members of Linked:Seattle? And you're probably in a much better position to answer that than I am!
