Today Facebook, Tomorrow the World

With a few deft maneuvers, Facebook is aiming to make itself the center of the internet, the central repository and publisher of what users like and do online. Facebook’s new tendrils will likely give what is already the world’s largest social network enough data to compete with Google for billions from advertisers who are hungry to spend their ad dollars on ads they can target specifically.
Facebook’s main lever to get all this data funneled to them is a simple “I Like” button, which websites can embed on their pages with very little effort. When a user clicks on that button, they signal to Facebook to add their vote on their user stream that they are a fan of this NFL player, this romantic comedy or that blog. Websites that embed some smart metadata (geared mostly for Facebook) into their pages let Facebook know what kind of thing a user likes, so Facebook can automatically add it to the relevant section of that person’s profile — with a link back to the original site.
