You may have noticed that LinkedIn has created a new feature called “Endorsements.” Much as Netflix prompts you to rate movies and Amazon books, LinkedIn is prompting you to endorse your peers. Because a lot of people have been asking me, “What the heck are endorsements?” I thought I would take a moment to explain what they are, how they work and why you might want to pay attention.

Let me start with some background. A few months ago, LinkedIn rolled out a new feature, called “Skill and Expertise,” that allowed users to tag their profile with a list of skills. This section remains active — just go to http://linkedin.com/skills to search for specializations like intellectual property litigation, FTC compliance or corporate law and add them to your profile with the click of a button. I recommend that lawyers go to this page and add up to a dozen skills that apply to them.
