LinkedIn started in 2002 and has grown with the development of Web 2.0. It has not only grown in membership, it has grown in capabilities and features. Grant it, they do not incorporate video uploads and VoIP, but they have kept up the the changes in how people now use the Internet to expand their options when it comes to their professional lives and networking. The purpose of LinkedIn is to expand your network of connections to build or enhance your career by providing you with access to connections beyond the people you know. It can help by showing you a map of the people you know and who they know that you might find useful in your search. I recommend trying it out, finding or inviting people you know, see who they know, and using the tools and resources to make a build a strategy and plan of action for your own career development.
