The inevitable end of this article's train of thought is that mediums of communication and places to meet people are dangerous.
The internet is like the street. You can meet people there. You can talk to people there. The big differences are anonymity and safety level. You can pretend to be somebody else a lot easier on the internet. You can kidnap someone a lot easier on the street. It seems like the internet is a place of many fewer possible evils, at least to me.
I wouldn't say "The Internet is Fire" is any more valid a thing to say than "The Street is Fire." The potential danger is not something new or "internet only," it's the same potential danger you face when you go into public. You might not be safe on the street, and you might not be safe on the internet. This Rita Ferrandino, who left AOL because she witnessed bad things that just so happened to occur on the internet, has, I think, overreacted. Perhaps she had previously considered the internet some kind of fairyland? Perhaps the bursting of her bubble will make her realize that there are no fairylands where we mundane folk dwell.
The "fire" of the internet is the "fire" of everyday risks. Not exactly a new concept...
