“Social Networks” are for making lasting connections between people who are related in various ways, e.g. family members, friends, colleagues, shared interest, fans, professional contacts, etc.  Some are better for making new connections with other network members, like LinkedIn, while others are more typically used by people who are actively connected in some way outside the network, like Facebook. Twitter is best used for broadcasting breaking news, event notification, your thoughts and movements, or links to other content to a potentially large group of identified individuals and providing a context for them to post responses and comments in place where others can see them.  A good use of this capability is to build confidence in existing customers with announcements of new deals or products.  Such services are widely misused as a mere reminder of the tweeter’s existence or for providing a digest of information that few people care about, e.g. “On my way to the airport.”Presentation Sites” like Flikr and YouTube enable the posting of picture albums and videos, respectively, of any length for free, to be viewable either by the general public or only those you allow.  Viewers can publicly share their unregulated opinions and responses as they wish.It will be important that you are plugged into multiple social media sites and use tools like contact management, videos and video email and desktop sharing.
