It's no secret that Viget is a huge fan of Gowalla. As an agency, we have more than 2,000 check-ins at our Falls Church office alone. The geolocation service gained early fans here not only due to its incredible attention to detail and design, but also its increasingly unique gaming component surrounding virtual items (e.g., the Moon Rock I recently picked up).
