Anyone can create a group on LinkedIn or another online social network and attach a logo, description but that is the easy part. Adding members, encouraging discussions, and monitoring messages can be more work than originally perceived.
Here are the reasons why LinkedIn Groups Don’t Work:
Self promotion. Group administrators must supervise discussions so that members do not monopolize discussions by offering their services as the main message unless that is the goal of the group. This is no different that people going to a live networking event and the first thing they say is BUY from me now. Discussion messages should mainly focus on analyzing hot topics, concerns or industry trends.
No promotion. Creating a group is not enough. Consistent marketing and communication to existing organizations is mandatory for members to join the online group and participate. Group administrators should encourage their members orally, link in email signature, advertise on website, blog, and other online social networking profiles.
No discussion. If nobody posts discussion questions or messages then the group just becomes a database. People that share similar interests and expertise can fine tune their knowledgebase by asking questions and receiving answers. Most discussions involve opinions which is great to see another viewpoint.
No members. There is such thing as a one person group but it is hard to communicate with just yourself.
