I love TED.com a lot too. Great speakers,new ideas.
As for myself I visit adage.com regularly
TED is too statist for my liking. I stopped visiting years ago, then some 3-4 years ago when that free cities guy spoke about his plan to develop a free city in Honduras, I watched that one video and it turned out even he was full of ideas of how state could plan free markets! That was the end of TED for me.
Related to the coin, I visit cointelegraph.com for Bitcoin news with a free market slant. Even though they don't have that many news, at least they don't irritate me.
Also I try to visit here for the same reason - the community is small, but good!
