Lately I've been exploring more ways to get involved with my community in order to network and hopefully generate some business. I've recently become interested in a site called Meetup.com. It's a social networking site for local groups. Based on your interests you can either find an existing group to join, or organize your own group. There are both social and professional groups on the site. Many of the professional groups tend to meet on a monthly basis to share ideas and network. Has anyone participated in any professional meetups or started your own group? I'd love to hear about your experience.
