I’ve written a lot about how cruelty has ruined Web 2.0:

Hate Mail and Spam
Why Do You Hide Your Identity?
Impulsive Web Rage
Anti-Social Networking
Sycophants in Rejection: Making Terroristic Threats

Is the legacy of Web 2.0 destined to be the marker of the anti-social revolution and repulsive online norms and memes?

I am always disheartened to realize just how much the “bringing
together of us” intellectually has actually distanced us emotionally by
allowing anonymous, vengeful, attacks from those who do refuse to own their own words.
