While we already explained Chatroulette to you recently, The Daily Show did a video (mildly not safe for work due to some language) that not only demonstrates how odd the site is, but how potentially dangerous it could be for kids.  Yes, it is all done with humor, but in his effort to mock the site, Mr. Stewart and his writers may have done the most effective job of demonstrating the problems with it.

Sit back and laugh, but realize … this isn’t too far off from the truth.
