Social networking has gone from a classroom thing between classmates to a desire to buy, use and visit locations associated with your favorite newsfeeds from your favorite likes.
Its only as good as the user in terms of you have to know what makes you happy and buy, visit and communicate accordingly. The Facebook is only a tool to help you do so.
How does this make money, they said the same thing about television, except there the ads are very broad based and not specific to the individual. Travel agent, party host, favorite sports guide, car reviewer, dating and work assistant, and money manager all possible with the right newsfeeds and when advertising realizes they can target specific interests they can get better results. When the user realizes what makes he/she happy they will be getting what they desire via this network I believe.
