Social Networking: An Addiction?

Today I was watching some videos from a Youube news channel that I found and subscribed to yesterday called SourceFed which is also run by Philip DeFranco (aka sxephil), one of Youtube’s most subscribed to individuals.  I came across a video that talked about Facebook and Twitter and how studies show that they are more addictive than alcohol and cigarettes.  I would have to agree because there are clearly a lot more people that use social networking sites than drugs, but perhaps in this case the word “addiction” could be replaced with a less extreme word, because an addiction is usually thought of as harmful, and though technology can do harm, it does not always.  Should we worry that people are becoming less connected in real life, or does social networking allow for a greater level of connection?
