Something to be aware of before you hit that like buton:
Facebook users are unwittingly revealing intimate secrets – including their sexual orientation, drug use and political beliefs – using only public "like" updates, according to a study of online privacy.
The research into 58,000 Facebook users in the US found that sensitive personal characteristics about people can be accurately inferred from information in the public domain.
Researchers were able to accurately infer a Facebook user's race, IQ, sexuality, substance use, personality or political views using only a record of the subjects and items they had "liked" on Facebook – even if users had chosen not to reveal that information.
It's developments like this that might hasten the development of private facebooks, after all why does everyone in the world have to be on one big platform generating handy research for advertisers and governments:
What comes next is an easy way for the generation of people who grew up on Facebook to create their own social networks, accessible only by the people they want to share it with.
When we look back, Facebook might look as crude (and as vulnerable to intrusion) as an operator controlled telephone partyline.
