If you enjoy writing, one of the ways you can share your knowledge is to use Facebook and/or LinkedIn as your very own blog. There’s no need to go to all the trouble of creating your own site. Once you have your profile up, you can use your social media sites to post your own content, and share other content that you deem appropriate for your target audience. And you can set it up to automatically post on Twitter if you have an account. You can include published articles, partial presentations and links to information valuable to your contacts. It’s a great way of raising your profile and demonstrating your expertise. On LinkedIn you can share it with your network, post to groups or send it to individuals.
