LinkedIn is a great tool for your career, particularly if you own your own business as through your network you can establish yourself as an expert in your field and extend your reach and exposure. But shock horror, you actually need to be active on the platform to get the most from it.  And it’s a platform where size does matter.  Remember, the more first-degree connections you have, the more second- and third-degree connections you have, making you literally one connection away from millions of people.
