I know we all hesitate to click on you-tube videos that are sent, but this one is something I really think we all need to know about. This is not funny or cute, but it's something worth watching, and being aware of. I found it by accident, but it has made me really think about these things more deeply. PLEASE WATCH IT. This is not political at all, but important to all of us. http://www.wimp.com/filterbubbles/
