"The echo chamber doesn't need any bad connectivity to function. Limbaugh's followers have full access to outside sources of information. According to Jamieson and Cappella's data, Limbaugh's followers regularly read - but do not accept - mainstream and liberal news sources. They are isolated, not by selective exposure, but by changes in who they accept as authorities, experts and trusted sources. They hear, but dismiss, outside voices. Their worldview can survive exposure to those outside voices because their belief system has prepared them for such intellectual onslaught."

"I have used Google Hangouts since the tool was first released, but my initial exposure to a Hangout on Air was during edcamp Home. Edcamps are typically held on school campuses, but edcamp Home allows you to connect with great minds in education from the comfort of your own home -- PD in your PJs! The organizers of edcamp Home completed their third event in July 2014. They work extremely hard to put this fabulous event together, an event that wouldn't be possible without Hangouts on Air and Google Docs for brainstorming sessions and scheduling. Having attended traditional edcamps in the past, what I love most about the "Home" option is that I don't feel as bad about popping in and out of sessions as I do in person. Even though you're encouraged to leave a room if you aren't "feeling" it, I still find it uncomfortable to up and leave in the middle of a face-to-face discussion. Edcamp Home eliminates this feeling of guilt because no one really notices when you pop in and out."

"Part of what makes emotional content so susceptible to spreading is that emotions themselves are contagious. Researchers have long known that people can "catch" the emotions of someone around them, so to speak, through direct exposure to that person's expressions and tones and gestures. They also believe this process of emotional contagion can occur indirectly--say, by receiving a forwarded video clip or article."
