Evgeny Morozov beats up on Jeff Jarvis's new book, Public Parts: How Sharing in the Digital Age Improves the Way We Work and Live:

Whenever he needs to explain something positive, his instinct is always to credit the Internet: it is the one factor responsible for more publicness, more democracy, more freedom. And every time he turns to darker and more difficult subjects—like discrimination, or shame—he announces that they have nothing to do with the Internet and are simply the product of outdated social mores or ineffective politics. In Jarvis’s universe, all the good things are technologically determined and all the bad things are socially determined. 

Jarvis's short response here.
