“Base your network on shared interests.”
another tip: Exchange physical business cards if you are self-employed and in job interviews . Make it easy for others to contact you instead of making them look you up.
My programmer daughter did not think she needed a business card because her information was on LinkedIn and GitHub. I convinced her to make one anyway to make it easier for people to see her abilities, contact her later, and remember her, just like Get-It-Done Guy says. She enjoyed the process and is motivated to make more connections so she can give them out. They came in handy at two recent job fairs.
What useful connection have you made based on shared interests?
