I have just started down the long road of Internet business networking. Yes, it takes diligence but I have seen good results. Jobs are posted and people are matched. I've asked questions and gotten great answers. I've made good contacts with people that I would have otherwise never met.
What experiences have you had? Are you part of any networks you would recommend? Do you have any hints to make the experience more useful?
I am part of:
LinkedIn (http://www.linkedin.com/)
Fastpitch (http://www.fastpitchnetworking.com/),
Plaxo Pulse (http://pulse.plaxo.com/pulse/).
If you haven't tried it and want to have access to good people, this is definitely one way to go.
Here is a link to a whole bevy of business blogs. While you will need to sort through them, it certainly gives you a view of what's available:
