Sure there are examples of negatives like manipulation of facts by people wanting to sway political opinion. The example of making theft easy & other negatives. But there are positives like this forum. How else would it be possible to share ideas, opinions, or express condolences with someone only known by an online name. Having accounts on facebook, twitter or that kind of interaction never appealed to me.
I can not believe what is going on for example The New Zealand tragedy they check his computer records and found he watched some social media and now they want to ban some different sites if he had watched CNN would they want to ban that too? You know the answer just one sided. Double standards against social media. They are so afraid you just might learn the truth.
