According to the Wall Street Journal today, Facebook, MySpace and several other social-networking sites have been sending data to advertising companies that could be used to find consumers' names and other personal details, despite promises they don't share such information without consent.
I do find it funny how people are shocked by this. It's a company on the internet that houses a wealth of knowledge about it's members. Who wouldn't sell that info to the highest bidder.
Besides people should know that once it's on the internet it stays on the internet.
