Are Social Networking Sites A Negative or Positive

I think social networking websites are a negative and positive. I say that because on a positive note you can meet new people and become more social with others outside of your normal friends. On the negative note you get so accustomed to communicating to others through computers that you feel awkward socializing in real life. I think there should be some distance from always being on those sites. Because like I said in my earlier point that it takes you from the real world and brings you to virtual life. It in my opinion hinders you from being with real people and you always need interaction with real people rather can computers. I think that there should be a limit on how often you get on these sites like Facebook,Myspace or Twitter. But that's a whole another blog that would deal with freedom of speech and freedom to do what you want. But in my conclusion these sites are good for the people who want to socialize but bad for the people who don't know how to distance themselves.
