Who's Who?

Mr. McBastard here. I've been on 20SB for about a year now, but I've never been active in the community.

I'm pretty new to Chicago and nigh friendless, so I thought the 20SB Meetup would be a good opportunity to meet some people and explore my new city.

So, I guess this is just to ask, who are the movers and shakers here? Who should I talk to first, and who should I watch out for? Who's the gossip? Who's the flirt? Who's the brains? Who's the trouble-maker (besides myself, that is)?
