LinkedIn has become one of the most useful social networking tools for professionals, and if you just aren’t comfortable using the site, taking an online LinkedIn class may be the answer. Classes will teach you how to get the most from the site’s features, and to feel comfortable using it; many older people still aren’t comfortable using social media. LinkedIn allows you to look for jobs, or if you are an employer, to post for jobs and browse resumes of potential applicants. The site allows you to locate others in the same industry, to network and exchange information and ideas; in short, to keep up with what is happening in your particular field of work. LinkedIn is easy to use once you have taken a class or two, is free, and can be especially effective for anyone who is self employed or a freelance worker.
