Getting back to the original topic... Other ways to network:

Hang out in FBOs and talk to flight crews that come in.
Start a business card collection from the folks that you meet/greet.
Go to FAA safety seminars, professional conferences (such as NBAA, Women in Aviation, AOPA, etc).
Meet people in person that you talk to via forums like this.
Ask other people you know in the industry to introduce you to other pilots.

Most importantly (in my mind), have a good attitude, stay humble vs arrogant, and be open to opportunities that might arise for learning and career. If you have these qualities, it's a lot more likely that somebody will be willing to spend their time "mentoring" you along the way.
