The Enthusiast Group is an exciting company built around providing social networking and citizen media platforms for passionate folks. For nearly 2 years now they've been building sites to support communities around adrenaline sports (YourMtb.com, YourClimbing.com, YourHorseSports.com, YourCycling.com, YourRunning.com). This has given them great experience in the world of social networks and user-generated-content (citizen journalism) including some relatively novel uses like Grassroots coverage of major events.
