Networking

Networking has been in the forefront of my thoughts lately. How can I find more clients; what's the most approachable posture when at an event; just WHAT will my introduction sound like.
While updating my calendar to reflect the upcoming Office Nomads events I ended up at Biznik (a possible Seattle start up I hear!? Loves that!) where the "Company Picnic" for Entrepreneurs jumped out at me. If anyone is interested in going, let me know 'cuz I think an event like this would be more fun with a partner in crime. Preferably and entrepreneur partner in crime...
I love the buzz in my head and the wealth of resources I'm finding online. Craigslist, Biznik and LinkedIn are resources one must use often.
