LinkedIn is the professional version of Facebook. It is an excellent professional networking resource. Many people use it as a job search tool; and entreprenuers use it as a powerful resource in the development, launch and success of their ventures.
On LinkedIn you can join up to 50 user-created groups from a list of thousands, absolutely free of charge. Not only do these groups allow you to connect with group members who could become future partners, customers, investors and employees of your business; but you also have access to the group discussion boards and news sections which provide more networking opportunities, answers to your questions and great advice!
