I saw this the other day and thought I would share this here for some of you who are looking for jobs. I myself haven't used LinkedIn much but I know people who do. From the article: "Basically, students can surf through various career paths based on school, level of education and dream industry." Good luck!
By the way, Mashable is a fantastic resource to keep abreast of news about social media (which I heart), and you can find them on Facebook. :)
