1. Go to Google Reader
2. Type this JavaScript code in the address bar:
javascript:antisocial('true')
3. Google Reader will reload and you'll see a simplified interface that removes the section "People you follow" and no longer shows shared items from your friends.
The setting is saved to your account, even if the toggle is not included in the interface. To go back to the standard interface, type this code in the address bar:
javascript:antisocial('false')
