This is such an inspirational site dedicated to Ideas Worth Spreading as their motto says. It contains videos usually between 10 and 20 minutes with talks/presentations from people with a message, an idea, or a just a different perspective on the world. It's quite interesting, especially the fact that you may find something you had never thought about before. A lot like YouTube except this is a little more .. educational and thought-provoking!

http://www.ted.com/The first TED Talk I ever saw a couple of years ago was this: Chimamanda Adichie talking about the
Danger of A Single Story. She is an African writer and warns us against looking at the world from one narrow viewpoint or to stop asking questions about the people and things we meet. It's a little different talk because she deliver it as a speech, most of the other speakers talk without a script and uses powerpoints and stuff.
I recently saw Eli Parisers talk on
"filter bubbles". And this is quite disturbing. It deals with the way Google and other search engines and social networks personalises our search results based on our search history so that we will only get 'relevant' search results and nothing of the stuff we never click on - even though it may actually be interesting. But we're locked in our own personal filter bubbles.
