Nineteen clicks of separation

It’s a small Web after all. As the six-degrees of separation notion says that any two people are only six introductions away from one another, researchers claim that any two webpages are no more than 19 clicks apart.

The Royal Society, a scientific organization established in 1660, this week published a paper that has found a similar model works for the Web as well as it does for people. Despite the billions of pages on the Web , you can get from one page to any other in about 19 clicks, according to Albert-László Barabási, a networking theorist in the U.K. and member of the Society.

Barabási used network science to model the Web, finding it to be a ‘small world’ of about a trillion documents connected by relatively short paths.
