So what if this makes me a nerd at heart, this site is really interesting. It's a collection of video lectures by specialists in different fields, mostly asking a question or explaining some issue. It's a nice, brief way of noodling around in the intellectual world without having to fully understand any particular field, kind of like a truncated version of college. I stumbled onto Five Dangerous Things You Should Let Your Children Do on YouTube, which led me to Why Aren't We All Good Samaritans, then Beauty and Truth in Physics.
