Groups are useful, however many people involved in groups are either just quiet observers or rambling conversation hogs. Control the conversation. Build and manage your own peer group that is information based. It sounds intimidating if you aren't a prolific writer, but here is how you do it. Create a list of 10 questions you wish you could answer in order to advance your mission. Form a group and send invites including those topics to others in your industry. Tell them you'll be covering these topics and ask them for input as well. This way people will join you on a meaningful journey and keep the discussions valuable.
