"Sarah, I think your example of Harley Davidson perhaps suggests that not all community managers can create a great offline experience for customers.  It's something that should be remarkable and unique and not simply a friendly gathering of people. By this I mean that an offline community should offer value and additional talking points for a customer.  Too many offline communities become another point to pitch to customers. If a community manager can make it much more about the experience (as Harley Davidson have done!), then it can make a big difference." - Josh Chandler
