Links may be the foundation on which the Internet was built, but they are not its future. "Likes" have become the new links that drive our connections online.
Links were also the basic way that search engines separated the wheat from the chaff. Websites optimized for linking and sought to raise their rank in search engine results by increasing the number of links to their pages.
In fact, the 'Page Rank' algorithm that addressed this web of links was the fundamental innovation that allowed Google to flourish.
