I'm pretty sure at this point that CoWorking is exploding in the US. This seems to be a new and rapidly expanding work paradigm and wondering how behind the ball the industries serving office workers will be before they finally note this and jump on the bandwagon with CoWorking specific products and services.
But anyway - Office Space CoWorking in Akron, Ohio. Located in a great old industrial mill building they appear to be running a wide range of events for their members. From seminars on backing up your data, to meetups with jazz, it looks like they have a strong work community going. Check them out.
