Follow up: When you ask someone in your network for something (like a reference, advice, an introduction) and she follows through, let her know what happened. Did you get the job? Did the idea work? Most people don’t do this either. I do all kinds of things people request of me and I rarely hear back about what happened. When I do, it is the exception, and I am thrilled. Once I got a call from an executive recruiter while I was driving; a referral I’d made had led to an actual placement, and she wanted to thank me. I almost drove off the road! That’s very rare, indeed.
