If you've ever seen me talk about networking, I maintain that GOOD networking isn't going out to "get" something. Good networkers look for opportunities to help people - to EARN the right to ask a favour.
My marketing hero, Seth, talks about this in his own way in the context of social networking. It's worth a couple of minutes of your time to watch (and thanks to Mark at The Fortune Institute for sending me the link).
