Having a LinkedIn profile is practically a requirement nowadays, but are you getting what you want out of it? Do you even know what you want? Are you seeking job offers, consulting gigs, requests to speak? Breitbarth says lacking a goal is one of the biggest mistakes people make when signing up for the professional networking service. "If you don't know why you're there, how are you going to come up with a strategy?" he asks. Once you decide why you're on LinkedIn, you can find details in the book on how to use the site's many functions to get the most out of the service. Green Leaf Book Group Press, $16.95
