Facebook is a social utility that connects people with friends and others who work, study and live around them. People use Facebook to keep up with friends, upload an unlimited number of photos, share links and videos, and learn more about the people they meet.
Like locked cell phones and copy-protected music, Facebook is on the wrong side of the open-network debate. Facebook is a sealed bubble. Facebook users are locked into Facebook, just as iTunes locks music fans to Apple's iPod.
