The Unseen Side of Social Networking

There are still many individuals who are yet to be convinced that social networking is a dominate part of lives today, and will be for years to come. In a recent article at the Washington Post, they discuss some new research that has surfaced that indicates that social networks are proving to be beneficial to today's health: by helping smokers networking with other smokers who are quitting. The research found that those who networked together were more likely to quit all together.
If this is the case, pointed out by the Harvard research group, then social networking could be put to use for other needs in society that are ill-addressed, such as fighting crime, safe sex and exercise. If social networking has proven to help networks of people quit smoking, the influence is evident. What other positive things can social networking be used for?
