Brooklyn Record reports that Coworking Brooklyn, a space share for freelancers in Williamsburg, is hosting an open house on Friday. We think this kind of cooperative arrangement is a great idea, with a lot of potential for independent workers. In fact, we're investigating other ways that cooperatives can benefit freelancers. We'd love to hear if you have an office share, a bulk purchasing group, a time share with other freelancers for the services of a consultant, or any other sort of cooperative arrangement.
