All websites connected by 19 clicks or less?

There's a saying that everyone in the world is connected socially through six or less people, and now Hungarian physicist Albert-László Barabási discovered that every single webpage is connected to any other in 19 clicks or less! Full details the Smitsonian.com Blog.
Barabási’s findings, published yesterday in Philosophical Transactions of the Royal Society, involved a simulated model of the web that he created to better understand its structure. He discovered that of the roughly 1 trillion web documents in existence—the aforementioned 14 billion-plus pages, along with every image, video or other file hosted on every single one of them—the vast majority are poorly connected, linked to perhaps just a few other pages or documents.

Distributed across the entire web, though, are a minority of pages—search engines, indexes and aggregators—that are very highly connected and can be used to move from area of the web to another. These nodes serve as the “Kevin Bacons” of the web, allowing users to navigate from most areas to most others in less than 19 clicks.
