All Bridges Are Weak Ties

When it comes to network diffusion of information or influence, all bridges (a line in a network graph that represents the only connection between two points) are weak ties.

Why? Because the stronger the tie between two individuals, the more overlap they have in friendship circles therefore no strong tie is a bridge.

This also means that weak ties are important because they can be the only way in which information or influence can travel. Indeed, removal of a weak tie does more damage than a strong tie.
