There used to be a HN meetup, but it stopped happening after a few months. A friend and I started Chicago.concat() which has been going strong for a few months and has a great group of people that show up every month. I have since moved to SF, but they're kicking ass back in Chicago. RSVP page: http://chicago-concat.gathers.us http://chicago-concat.gathers.us
