Facebook plans to take over the entire web with a universal "like" button
This is a brilliant plan for Facebook, from a business standpoint. With integration across other sites, Facebook could very well become the default social presence on the web, totally obliterating its competition. Thousands of other sites will be sending data back to Facebook, which can then monetize the information in any way it sees fit. Data about your activities on the web is valuable stuff, and Facebook knows it. Let's hope the privacy settings keep up with the new features.
