    This paper introduces the idemetric property, which formalizes the idea that, in many social and information networks, most nodes have similar distances between them. The paper shows that samples from standard generative models (preferential attachment, etc.) are idemetric in our sense. The paper also considers algorithmic applications. For example, we prove that a single breadth-first search provides a solution to the all-pairs shortest paths problem, so long as one is prepared to accept paths which are of stretch close to 2 with high probability.
