““Like Newt Gingrich shifting the focus from local to national, social media has transformed politics from the public to the personal. Whereas, in the past, people associated with their friends and families based on proximity, common history, or blood relation, social media gives the person the power to structure their relationships based on common interests and shared political goals. This grouping, often called an echo chamber, creates a world in which people are rarely confronted by disparate opinions or facts and ensures their persuasion goes unchallenged. And the more they become entrenched in their opinions, and the more they see others touting similar belief structures, the more the user's beliefs deepen.””
