3. Social Networking

Social networking technology has helped people connect find things that they would not have been able to do without social networking. In his article "Social Networking Technology Boosts Job Recruiting," Frank Langfitt writes about how an employer used Linkedin, a website made to be a virtual network for professionals, to reach out to an employee at a different company for an open job position. Social networking has helped employers cut out the intermediaries to get contacts and has provided employers access to a huge network of contacts.
Social networking technology has also helped society become more efficient. In the article "In India, Using Facebook to Catch Scofflaw Drivers," Heather Timmons writes about how social networking technology has helped traffic police with their job. The New Delhi police began a facebook page to have people express their opinions suggest their changes about the traffic. Eventually, people began to uploading photos of lawbreaking motorists onto the site which has helped the traffic police to issue more tickets and made drivers more cautious.
But, there can be a dark side to social networking technologies. In the article "Who Cars About Facebook Privacy? Students Do," Marc Perry writes that the "engagement with privacy settings increased significantly" from students between 2009 and 2010. Apparently, some troubles have come up concerning the privacy of facebook users and caused the users to be more cautious.
As for ways these technologies may evolve in the future, there does not seem to be anything that has not been done already.
