1- If the Patent was just *granted* then it was submitted a long time ago, maybe even before Facebook came out.
2- Patents are for specific ideas and methods of doing things, not general, vague ideas. There might actually be no conflict. After all, Amazon does have a lot of social networking features in their website (and Kindle) but they are all intended for sales and support, not for comunication. While some companies and celebrities are using Facebook for marketting, most people use it as a communications tool.
3- The people most opposed to patents/copyrights are the ones that never created anything of value in their lives.
