If you are a business professional it may be something to consider if you are not yet. Here is my page I see LinkedIn as your professional calling card and bio. There is no better way to build your professional network and showcase your talents. And also to see others whom you are doing business with or more important - who you plan to do business with.
Also, its a great place to build your reputation in a positive way. Sure you have to really lay yourself out there for others to view, comment and remark. But why not? We all want to be liked and recognized for having high integrity and to be trusted - so let others comment about you, they are your best promoters.
