How to network effectively?

[tehuskey513]

I'm currently on the hunt for a new job. I've been told that only 5-10% of all job openings make it to the classified ads and online job sites. The rest are filled through internal contacts or through networking. How do I do that efficiently and effectively though? I graduated college in 2006, so I'm still pretty new to the world of work, and I don't even know for sure what career path I really want to go down, much less what contacts to make to get there. All the online articles I've read seem to assume you already at least have some idea what you're doing, and I don't. I've got (what I consider) a pretty good resume writing system down, but I'm considering going to a professional resume service for help. I guess my question is, once I have the winning resume, who do I talk to? Where are these infamous contacts that I need to be making and how do I get started?
