in trying to respond to this, I really don't have as many "interesting" sites for you guys. My typical visits go to NYTimes (
http://www.nytimes.com/), NewScientist (
http://www.newscientist.com/).
But a very amusing one is called Overheard in New York (
http://www.overheardinnewyork.com/), which is exactly what it sounds like. No audio, no video, but still hilarious as posters (truthfully or not) recount conversations they've heard in the city.
Facebook, by the way, is a total waste of time.
