The story of tribewanted.com has captivated me for years. Ben Keene put out a call for people to join a new online tribe in 2006. He wanted to build a sustainable tourism community. For the last years he has been doing so with the help of this online community, in Fiji, Sierra Leone and now in the Umbrian hills of Italy. Together they have generated more than 5 million in revenue, re-invested in local villages and created over 50 jobs. The beauty of these projects is that anyone can be a tribe member and experience these real-world communities. Learn more about it here.
