Your name, profile picture, gender, current city, networks, Friends List, and all the pages you subscribe to are now publicly available information on Facebook. This means everyone on the web can see it; it is searchable.
This represents just the latest instance of Facebook violating the contract it holds with its users. This is no small matter, either. Lots of people will have very real and valid objections to this arbitrary change to what's public and what's private on Facebook.
