One of my favorite sourcing techniques is the targeted e-mail. Let me walk you thru a campaign:
Step 1: Use an X-Ray Search to target a person.
Step 2: Look them up on LinkedIn
Step 3: Communicate via social media
Comment on their blog. Tweet at them, Facebook friend them, find them on Quora, About.me --- reach them wherever there might be some non-professional info about the person.
Step 4: Send an e-mail that’s personal, funny, attention getting, original.
