Check out the movie Final Cut with Robin Williams. It's about a time when people have cameras embedded in their eyes that record EVERYTHING, then someone edits together a video of their life. It deals with the fact that these editors get to see literally EVERYTHING (sex, crimes, etc.) that the people do. Very interesting.

Justin from justin.tv basically decided to record his entire life with a head-mounted camera as what later pivoted to the company we know.

Which has not that much to do with the founding idea. Instead tons of gamers are streaming/watching playing League of Legends or Starcraft.

Well, they are streaming what they are looking at...

This sounds a lot like what was described in the UK miniseries "Black Mirror": in short, record your life.

If anyone hasn't watched this BBC show: http://www.imdb.com/title/tt2085059/

I absolutely think this is the kind of show (3 episodes so far) that's aimed at the HN crowd. Completely blew me away.

Just a slight correction: Black Mirror was produced for Channel 4 (as opposed to the BBC).

yeah i was thinking that while watching the demo. cool, verging on creepy.
