FOAF-style network

Just when you think social networks could not get more innovative, think again. When I was first exposed to this idea, "friend of a friend," I thought about LinkedIn. I know they are different, but I feel there is a minimal amount of social "business" networks. With "friend of a friend" may change the whole game of getting employed. For example, the whole "interview process" begins with getting recognized. Being recognized, in my opinion is the hardest part in getting a job. If your resume is not impressive, and your cover letter is just average, consider yourself unemployed. However, you take this same instance, and your references are all presidents of major companies, you may have a shot. Your best references in the near future may come from a "FOAF" network. People build credibility in numerous ways. With a FOAF style network, it is just another way to get recognized. In this economy, the unemployed can use all the help they can get. Also, this may benefit businesses all around the world. So much money is put into research and background checks to make sure the individual they are about to hire is the right choice. With this style of network a company may better understand the type of person you are through the people that you know. If it's a social network I am going to assume it's free, which takes much of the economic pressure off of research departments.
