One of the major criticisms of social media is that it's disconnecting us, as individuals, from society and from real physical interactions.

But if a key element of 'tribe' is communication and connectivity then the digital world arguably holds unlimited bounds for tribes.

Mumsnet for instance has changed how we view mums as a social group. While marketers and advertisers may have seen them as a target market, they probably never thought they would be an ever-connected all-powerful tribe who could even make politicians quiver in their boots.

In this weeks' episode of The Digital Human, Aleks Krotoski asks if rather than separating us, the digital world is helping us revive old tribal connections.

If the internet has heralded the death of distance, what do these new kind of tribes look like? And do we relate to each other in different ways now that so much of our lives are lived online?
