"What happens if I don't clean my room?" my son, Taylor, recently asked me. He is fascinated by the concept of consequences. Just as children respond well to consequences, so do professionals. So instead of looking at the benefits of LinkedIn or the fact that, according to Greentarget Global LLC and Inside Counsel, 67 percent of in-counsel use it on a daily or weekly basis, let 's weigh the negative consequences of ignoring the site.

You may inadvertently ignore messages from important contacts. A law firm partner ran into a friend who was in-house counsel for a major company. She asked, "Why didn't you ever respond to the message I sent you on Linked In last month?" He replied, "Why on earth would you send me a message on LinkedIn — I never check that!" Ignore all the invitations sent to you via LinkedIn, and you might miss messages from people you don't want to alienate.
